Colin/Ginny
I don't know if he will. Have you met him?
Listen. Poor Maria can't help who she catches feelings for. That's just an unfortunate after effect of a good snog.
Is Ron a good kisser? I never knew.
It's gross to you because you're his sister, but it's probably just as gross to Maria that you're snogging her brother all the time. I'd be grossed out if someone snogged Dennis. It's a sibling thing...
Also, you and Maria look a lot alike so it's a little weird standing outside that both of them want to snog girls that look like their sisters...
