i did something mean to my lab partner

so there's this chick i work with on a project, she's way too into being the perfect student and always trying to one-up everyone else. like it gets really annoying how she always has to be right all the time and never listens when anyone else has ideas. so we were working late in the lab last night and i was getting super tired but she kept pushing for more data and stuff, wouldn't let up at all even though i said i needed a break already several times. well finally after like an hour of this nonsense i had enough and just got up to leave. as i walked out she started lecturing me about teamwork again, really pissing me off. so before i could stop myself i grabbed the box of petri dishes next to her station and tipped them over right onto her project samples - total mess. watched with a smile as everything went sideways because she couldn't handle a little pushback. i know it was wrong but honestly i felt kinda awesome for sticking it to her like that, took back all the stress of dealing with her crap this whole semester. yeah totally regretted it later when our prof called me into his office but man it was worth it in the moment
