So a few weeks ago in choir we got a new kid. I was pretty much the first choir student he met, because I'm in charge of uniforms and I had to fit him. I think he likes me, because I feel like he's always looking at me, and he teases me a lot, and he'll draw my attention to him if I haven't noticed him (He's yelled across campus for me before). Does he like me? Should I ask him to formal?
