Year 1
Dear Evans
Happy birthday. No, the present is not an engagement ring – well, it doesn't have to be. Of course I'd love to marry you.
But that's beside the point! The point is, I bought you this ring in Diagon Alley. It's a mood ring. The bit of paper it's wrapped in tells you what each colour means. I bet you're pink at the moment (love). I am blue (sad), because I haven't seen you in soooo long. Sirius thinks I'm a sap because I've only known you for a year, but I believe in love at first sight. Do you? I hope you don't, because Remus says I made a bad first impression. But hey, what would he know, right? He's never had a girlfriend either!
I remember it really well, because I knew you were the most beautiful girl I had ever seen. Plus Sirius pointed you out, because he thinks it's a crime if you don't go out with a girl from your own house, and he wanted to bags the prettiest one. He didn't though, I got there first. I had just met Sirius, and we got on really well, so I'm sorry if we looked a little bit crazy. We're not always like that, I promise.
Anyway, Hogwarts term starts soon, which is very yellow (lucky). We should meet up in Diagon Alley to buy our things. I'll write you another letter to check that you can, because bro's before... Um, girls.
Love your future husband/boyfriend,
James Potter
