"I prioritize safety, and a big pet peeve of mine is when others don't follow protocol. I've noticed that this is especially prevalent with those who are disorganized. I had a dorm mate who was also a chemistry partner a while back. Not only did they not carefully store away compounds when they were done with them, which presented all sorts of hazards, but they never did the dishes, and this person was just messy. Honestly, they were lucky they had me around. But I managed it well and just picked up as I went. Oddly, they followed suit after a while. Osmosis, I guess. Otherwise, we got along great."
