Input: Text: quick backstory: i am a duel enrollment student (still in high school but goes to college full-time) and don't have my license so i bike home. 

now let's get to the fuck up. i was riding down the sidewalk and up ahead was a golf cart blocking the way. the man who was using kindly moved it out of my so i could get past. as i go by, i give him the nod and say "thank you" just to be courteous.  well he didn't really give me that much space so as i was saying thank you, my goes into the grass and i quickly try to readjust, resulting in my tire hitting the side of the sidewalk and me falling off my bike. i looked like a complete dumbass and just laughed to myself and kept riding.  luckily, i don't take myself too seriously, so i wasn't that embarrassed.

TIFU by being courteous
