this wasn't today, but last spring. me and my friends at college were getting drunk in my friends room. we smoked some grass out the window and we were having a fun friday night. it was one of the first warm nights of the season so we decided to go outside and run around campus. as we got closer and closer to the student center quad, we heard people talking and music. we started running towards the sounds.
when we got to the quad, there was some type of event going on. there was a live dj and we dove at the table with the left over pizza. we were sitting on the steps after we finished the pizza. it was so satisfying, me and my friend, kevin, decided to smoke a cigarette. 
a few seconds after we lite up, another student comes up to me and says, "sorry, guys, but you really shouldn't be smoking here. this is the all night walk for breast cancer. it's okay, i smoke too, but i don't think this is the right place".
me and kevin quickly put out our cigarettes. so, tifu by accidentally smoking a cigarette at a breast cancer walk. go me.
