I went to yoga class today and chose a spot in the corner of the room to put my mat. I got all situated and sat down, when a woman I've never seen before walked into the room and without missing a beat proceeded to tell me that I was sitting on her mat. I explained that it was my mat that I brought from home, but she kept going on and on about it. The lady sitting next to me explained that she had moved the mat, after which the woman said my mat looked exactly like hers. She got her mat back, and it was gray and thin. My mat is black and thick. Whatever. I didn't sit there and say nothing. When it was clear she wasn't going to apologize, I told her I resented her accusation. That ended the exchange, thank God, but I can't help but wonder if she has mental problems or something. She certainly was rude.
