I'm not going to write some sappy letter about how much you mean to me because we both know I'm not into that. But, really, you do mean a lot to me.
We've had some pretty good times over the past year and I'm still hoping that we could actually get together and and do cool friend stuff someday.
I don't really know what I should put into this letter. It feels far too formal compared to our conversations, so...this is it, I guess?
