About 15 years ago I was in a meeting a was sitting next to this women I knew and always thought was nice. She ends up putting her leg against mine under the table. I thought she MAY BE making the move on me. I was like "Oh Crap, what do I do". Should I not move my leg and see what happens? Maybe she is making a play???
She kept it there for about 30 seconds and then moved it and said "oh sorry I didn't know that was you". I felt so stupid for even thinking it was deliberate.
