I usually sit alone in lectures, I've noticed whichever row I sit on, no one else will sit on that row, they'll sit on the others. I don't think it's hygiene because I shower everyday, and brush my teeth twice a day. I'm quite dressy in terms of style (possibly overdressed sometimes), and my hair is usually neat, straightened etc and for makeup I only really wear eyeliner, mascara, lip gloss and some bronzer.. I don't think I look threatening or something.
I met one guy in my lecture ages ago and we've talked frequently, I was sat alone again and he actually came over from the other side of the hall to talk to me that day but still sees me at the beginning and sits elsewhere. I know it's not a big deal but just something I was wondering today.
