What to talk about in a letter to your boyfriend

My boyfriend has moved to Arizona for a month from Canada and I promised to write letters, I have to write first so he gets my address, and i'm stuck on how to start it and what to write about. We've been dating for 3 months, he's 18 and i'm 17, any suggestions?

Maybe start off by mailing him a little care package of homemade cookies or something like that. Then you could just stick in a little note that says thinking of you. That'll give you a few days to think...

Make lists, like top 10 things that remind u of him, or are more fun with him, or that bite about being apart.

Talk about what you miss, talk about how you've been. What life is like without him. Just write about anything that is from your heart.
