Input: Text: so this fuck up happened a few weeks ago, but only now has the shame subsided enough for me to post this...

so a while back, i decided to slum it and go to my first music festival (before i got too old to enjoy it - i mean, eww, dirt). it was pretty standard - music, tents, alcohol, bit of rain... went with a largish group of people whom i knew relatively well. one of the younger guys in the group was an graduate from work (good friend of a friend). i knew him fairly well, but had never really thought much of him - he was like a little annoying brother. harmless. let's call him jon.

anyway, the day passes. i'm having fun. i'm enjoying the music. even the toilets are only fractionally creeping me out. it's getting more and more boozy and i'm starting to forget how to walk straight. as per all great festivals, the heavens open up and i run (crawl) to the nearest shelter, losing all my friends in the process. however, i do bump into jon and we excitedly greet each other in the way that only the truly trashed can do. i don't 100% remember what was said, but it was something along the lines of "i fucking fancy you throwaway" and me responding "oh yeah? i'm going to take you home!"

so i did. bear in mind that this guy is 7 years my junior and he's a flipping graduate at my work (setting a good example indeed) - my drunken mind convinced me that it would be a great idea to take him to my tent for some action. it was wet and dirty (literally, due to rain and mud) - we had pretty horrible sex, followed by him rolling off to one side and proceeding to vomit (in hindsight, my ego probably should've been bruised by this). 

i'm feeling pretty drunk and tired at this point, so i told myself i'd sort it in the morning... so i fall asleep despite having jon and a pile of his vomit next to me. cue the next morning - we are rudely woken by the glaring morning sunlight streaming through my tent, and i had to stifle a scream as my memory returned (and jon's hairy arm wrapped around me). i checked that all my limbs were intact (they were, phew) before i surveyed my surroundings. then it hit me - jon had vomited in my bag. 

vomited. in my bag. my bag with all my stuff in. my bag with all my clothes in.

you see where i'm getting at with this fuck up?

i spend the next 30 minutes trying to salvage an item of clean clothing and failed. i chuck jon out despite his hungover protests. i ended up having to ninja my way to the showers to "shower" my entire weekend wardrobe (praying that chunks of vomit weren't going to block the drains). it was awful. it smelled awful. the vomit was red wine vomit. and i was hungover.

for all my efforts, most clothes were vomit chunk free, however all had strange patches on due to the red wine. i also tried drying my clothes outside the tent, albeit unsuccessfully due to intermittent rain. had to wear slightly damp and slightly stained clothes for the rest of the weekend...

and i've not seen jon since.
