Not sure what to do about this crush...?

He definitely likes you and you like him, and since you're neighbors and your parents probably know each other it wouldn't be a hard relationship. And I'm 98.9% sure he won't turn you down. And he flirts with you, you know? If any guy flirts they're trying to get you attracted so you won't turn them down if they ask you out. GO FOR IT, GIRL! o(^_^)o
