Other girls haven't seen you smiling like I have.
Other girls haven't seen you go all silly and crazy at 3 am
Other girls haven't heard you singing and laughing at the same time because you know it yourself, you are terrible at it.

I know that I'm not like the other girls because I know more than your best friends will ever know about you.
I know that I'm not like the other girls because of the way you look at me and tell me everything what's going on in your head.

I know because I have never been like the other girls. Never.
