The other day I was at a concert. These two girls were touching each other a lot. Like holding each other and laying their head on the other's shoulder and sitting so close together their thighs were touching. About a week ago I saw two dudes sitting that close together on a bench, but when I overheard their conversation, those two dudes were gay. I thought that maybe these two girls were gay, but then I overheard them whispering about how hot a guy was. If those girls are not gay, why do they do that?
