Letters to Kevin

So, I've been getting weird letters in the mail for months now, and I have no idea what they are about. There is no return address, and no name, just "to Kevin" and my address. He says he knows me, but I have no idea. It's all kinda weird, so I've been typing them up and putting them on an alternate blog site "http://tokevin-randomletters.blogspot.com/" I only have a few up right now, but I'm trying to get them posted as quickly as I can, because the more letters I get, the weirder it gets. Check it out.

Thanks!
