<human>: Provide a brief overview of the text.

There is this girl that I have a class with and see her every day at school. I am 15 in high school and have never had a girlfriend before, but I am not sure about her.

We talk quite a lot in class and in between some classes, and we are always smiling and laughing. In class she jokingly kicks my leg and also occasionally touches my arm. She talks to me a lot in class and as I said before always laughs and smiles. 

I don't notice her playing with her hair or fiddling with anything but I might not be paying attention. I feel like she likes me because she doesn't act like this to the other guy at our table, but I am not sure about other guys in school.

I know I might just need to do the manly thing and ask her out, but if I knew that she liked me it would be a huge confidence boost as I am a pretty shy guy. Any advice?
<bot>: I think she likes me, but am not sure. There are signs but I don't know if shes likes me or is just friendly. Read post for details. Any help appreciated.
