I went to a fitness class today (only 1 other guy in it, about 60 girls... SCORE)... anyway we had to share mats with a partner, so I selectively partnered up with a really hot girl there and hit things off ok (had her laughing and rapport built and all that good stuff) and she was smiling at me all the time. When the class was over I told her I'd add her to facebook (I usually go for that over a number in a class environment or anywhere were I'll definitely see the girl again). When I said this she blushed and kept smiling. IOI or IOD, since blushing can sometimes be bad (e.g., if she was embarrassed)... Any ideas?
