I have a girl in my sorority who I swear is viewing shy! When I come into the room, she's swimming happily around at full colors (she's really pretty teal and purple), but if I sit down on my stool and watch the fish for a few minutes, she stripes up! That fast! She's right up there at the front of the tank with the other girls watching me back, but apparently the simple act of someone watching *her* wigs her out a bit!
What quirks have you noticed in the way your guys or gals act?
