So I'm a 22 year old not good with knowing who's a lesbian and who's not. But I sometimes go to my little sisters school to pick her up and her ex teacher is always looking at me I don't know if shes gay or not I do know she has 2kids but every time I can see shes looking at me from the tip of my eye and she always does that and other times we just look into each others eyes but I get nerves and I turn around. What I want to know is what is up with her I need help with this or is this just in my head
