So, it's been some time since i've had a crush on a girl and I guess it's sort of exciting to have a new one. Anyway, her name is Hannah and she is the most adorable little girl that Ive ever seen. She is three grades below me, and i'm not really sure if that's a problem. I know her sister fairly well, whom I sit with at lunch sometimes, and sometimes Hannah will come over to speak with her. This is the closest i get. Her sister and I have had a brief conversation regarding her once, like, "have you met her before?" or, "she's mentioned you before." Anyway's, sometimes when i pass her in the hall at school (which is rarely since we have very different classes), we will smile at each other and it gives me major butterflies. I'm trying to think of a reason to go up and talk to her, but i cant really. Any help?
