I'm grumpy and sick

So I’m doing a research project on lesbian social life, with special focus on the disappearance of the lesbian bar. And it sort of sucks to go to the lesbian bars by myself when my friends bail on me.

One of my first insights is that it’s hard to make friends at these events. People just never go alone. It’s a little hostile. 

Why are lesbians so clicky? Why don’t strangers approach each other?
