One time in a college chemistry class a woman came over after we were done doing the lab for the week and bunch of us were hanging around doing the packet of work on it. She had gone around and talked to most of the other people there first, and I assumed she was asking to get a copy of their lecture notes (it was a common thing in that class because the professor encouraged it a sort of shared learning tool), and then finally she got around to me. Turned out she was asking for help with part of the work that apparently everyone else was also struggling with (also common, because most of the people who stayed after labs to work on it then and there were the people who struggled; for anyone with chemistry experience, the struggle was remembering how electron shells work on large atoms). I helped her out because I knew how to do it, and showed her the simple chart that I used as reference when needed and she copied it down, and it was all good.
When she was putting her stuff away to leave she gave me one of the weirdest and probably the best compliment I've ever received. I'm paraphrasing here, but basically she said she was glad she'd worked up the nerve to ask me for help because she'd been afraid to do so before due to being intimidated by me after seeing me answer lots of questions correctly in class and being one of the only people to ace the first quiz thing we had. It was really odd, but one hell of an ego booster.
