What are some tell tell signs of you liking someone even though you try to hide it?

[Surely]

You always find a reason to get near them and hope that they notice you. You hope that they look at you so you can show your pearly whites. You know a lot of their likes and dislikes. You play with your hair when you are talking with them and blushing. You dress to impress them. Plus many more if anyone is observant.

Finding a reason to get near them , hinting to them that you are interested in them , being a little flirty basically letting them know you like them but you want them to make the first move

Boners- seriously, though, I would say looking at her and looking away if she looks at you.

You look at them and can’t stop doing it
