Dating Help

there's this girl i like at my after school samba band (don't judge me i'm a huge f**king nerd) i can't talk to her because straight after i have to go to an art class (like i said a huge f**king nerd) i can't talk at the begging of the class because we get straight in to playing.

She doesn't go to my school and i don't see her anywhere else, pls help
