I still think she could have said something to you too - or given you a card, etc. But it's so awkward when people don't know if their feelings are reciprocated or not, especially if they're friends already and don't want to risk their friendships! Especially when they're young.
No she didn't do anything wrong and she tried, she was just very sweet and a little shy. And I was an idiot. Anyway, the point is that sometimes people do not understand that someone likes them.
