Unbelievable

I didn't don't think I could can accept it when my best friend Jia told it to me. This morning, Jia told me that two girls in our faculty were lesbian.LES. And then,I was shocked. I didn't know don,t knew why it surprised me although I understood i understanded it was a common phenomenon.
I have (always? never?) ever heard about news about lesbian people LES, so I and didn't think it was crazy. But when it happened at my side, I found that I couldn't finded i can,t understand it. I swear that I didn't don't look down on them this. I just couldn't can't accept it.
