Can someone give me any ideas for a "asking a girl out" letter?

I know it's kinda childish but im still in 8th grade and im sure some girls still find the love note thing kinda cute, am i right? Well could someone give me any ideas on what to write on the note? Something that would make her go "awww" when she reads it? I know it's better when it comes from the heart but im completely blank.
