I agree about the public displays of affection... Go get a room! (Even worse if they do it next to a stairwell) But yea, some people think being gay is a "choice" but I know it's not. Some think that people are bi to get everyone, but that's just not true (Most of the time)
Pet-peeve - Breast feeders in public! YUCK! (Especially in the food court) I mean, I respect your desision to breast feed your baby, and your baby may get hungry while out, but couldn't you have pumped the stuff at home? Don't do that while I eat!
