Input: Text: my wife and i pulled a float in my town's christmas parade today. for the most part, things went pretty well. nobody fell off, was run over, and we didn't have any mechanical problems. for a few hours, i held a smile and repeated the same wave over and over to the thousands of people lining the route. i called out "merry christmas!" so many times that it stopped being words and just turned into a memorized sound. to entertain myself, i'd occasionally mix it up. "merry christmas, film in landscape, not portrait!" i might yell with a smile to someone video'ing the parade. "merry christmas, buy a house!" (the float was for the realtor group my wife's is in) to someone else a few blocks later, and a couple times i threw in a "kerry mixmas!" because if anyone noticed, how could they be sure it wasn't just their hearing? as far as parades go, it was pretty smooth. afterwards, though…  

as these things often do, it ran late and she had an appointment with a client so i volunteered to drive the float back to where it had been constructed. we swapped keys and she texted me the details. "here's the address. when you get there, go left", she summarized afterwards. the way she described it, i had the idea that i'd go straight ahead into a driveway then take the left fork of a y. we parted and i trundled off, taking the cargo truck with float where google maps told me. i saw a driveway where i expected but as i pulled in, i realized i had misunderstood her instructions pretty thoroughly.  

there was no y, and as i passed the point of no return i saw there was an actual separate driveway a few yards west of the one i'd taken. the place where they'd built and staged the float is, i discovered, also an "event location", the kind that hosts all kinds of parties and stuff like that. had i understood the directions better, i could have snuck around the back through the service road that bypasses the main building, but that's not what happened, i took the main driveway and an 'event' was in progress.
also, it wasn't a party or a barn raising or quinceañera, it was a funeral.  

scene: you are grieving with a couple hundred friends and family. it's a solemn affair (as is the custom when the departed is liked) and as a group, you are all sharing your memories and sense of loss in an orchard. the beauty of the surroundings comes with the quiet you can only find away from the city. uncles, sisters, cousins, friends… this is a chance for everyone to reflect on someone who touched all of your lives and share in the sadness of their passing. around you, nature reminds you that even when there's loss, life continues. the healing process teaches us that death is an integral part of life and we must all face it at some point, and sharing the grief helps us recognize how important it is to appreciate the limited time we have toge-  

you hear a motor. maybe someone's running late? the engine gets louder and now you hear some branches squeaking past something. somewhere in the back of your mind, you understand that this is not a compact sedan but something larger. it isn't until the front of the large truck noses around the corner that you understand this isn't the late arrival you were expecting.
around you, conversations peter out and everyone starts looking in the same direction. formal, dark dresses, black suits, children fidgeting with unfamiliar ties, they're all turning to watch because... suddenly parade float.  

back in the cab, i realize that i'm committed. there is no place to turn around, i have to go straight ahead. as i get closer, the crowd slowly parts to let me through, and i know that i do not belong where i am. this is not the plan we had worked out earlier, but i get the idea that stopping to revise would be even worse so i need to blaze on through. i'm hunting for something in my tiny social skills toolbox to provide guidance, and i've got nothing.  

as i pull the cheerfully decorated parade float past the silent crowd of mourners, my brain suddenly grabs onto a new the plan with the desperation of a drowning man reaching for a rescue buoy and the "parade route" program fires up. i'm pulling a float, there's a giant crowd... i feel myself starting to slip into this groove and i fight it. i do manage to stop from parade waving and in a bit of luck, my windows are rolled up so they probably don't hear me yell "merry christmas", but the giant fake parade smile... the more i try to stop it, the wider it gets. fueled by panic, i can't turn it off. the crowd, they don't look angry, they certainly aren't smiling, but they stare back blankly it's like they're trying to process what they're seeing. this cargo truck rumbling past them is covered with sparkling tinsel everywhere is pulling a long trailer behind with huge toy-block style letters spelling out 'realtor'. the float is full of giant toy story characters. the t-rex, buzz lightyear, sheriff woody, slinky dog... they sway slightly against the oversized display presents and candy canes as they pass through the crowd of grieving people but unlike their driver, they aren't making accidental eye contact with almost everyone in the crowd.  

approximately one eternity later, i drive out of the courtyard and join the service road i was originally supposed to take. i can't bear to look in my mirrors, but i can feel a hundred-plus pairs of eyes watching me. a few moments later, i'm out of sight and start breathing again.  

ditching the truck and float in the pre-arranged orchard, i head back home in my wife's car. "i drove a parade float through a funeral", i text her.  

"😳", she responded.  

yeah.

so it doesn't sound like i will be driving the float next year.
