I have never been great at reading a womans signals. So I am in a hotel tonight... I decided to order in room service so that I could watch a hockey game tonight (eh!) To set the stage - I am wearing a gray tee-shirt, and gray sweats (avec under ware - nothing poking out). The youngish girl maybe 20 years younger than me brings up my dinner. I fill in the tip and sign the bill and when I look up to hand the bill to her I notice she is now blushing very noticeably. What was she thinking about to cause her to blush? Surely she was not attracted to the old guy in sweats and tee-shirt?
