Crushing on someone I SHOULDN'T BE CRUSHING ON

Okay so.

I live in a dorm. And I have two roommates. For spring break I went to one of their houses in LA. And I met her family. And her younger brother is so cute. Even though we only spent a week there I now have a huge crush on him, over a month later. The problem is, well he's her brother, but he's also 16 and I'm 18. I know there's a legality issue there if anything ever happened, but like don't worry I doubt he would ever look at me romantically or otherwise. Honestly I just can't believe my life has come to this and I needed to get it off my chest 😂
