I went to a coed baby shower that followed choir practice last night. We were all standing around talking and after about 30 minutes or so I noticed that all the guys were gone and it was just me and 8 women sitting around talking about babies, kids and pregnancies. Although I was in obvious guy mode (all drab), it felt nice to be included and to feel a bit like one of the girls.
I think women are a bit flattered if a guy takes an interest in thier conversations and joins in respectfully. Anyway, it made for a great night.
