When a girl does this what does it mean?

i was looking down & doing my work & then when I looked up I saw the girl i liked looking at me & smiling then she looked down at my chest while still smiling then she looked up at my face while still smiling so I just looked away..then when I was talking to one of my friend I couldn't really hear him cause I had my headphones on & he said justin did you hear what I said & i said no. Then I heard her telling her friends that I crack her up and said that I was quiet but funny. Then later I heard her telling her other friends again that I'm quiet but funny. Then later i saw her looking at my direction

Awww how cute.

Don't over think it. She's into you. Approach her and start up a conversation.

This is definitely true just don't overthink it and start a convo. Since it seems you're in the same class (I'm guessing you are) you could start it off with that something like asking her how she's finding the subject and could even make up a lie that you need some help understanding it and ask for help or offer help to her if she needs it.

hope it helped at least a little 🙂
