Does this sound like an alright letter to send a friend..?

Sounds good to me. Just make it clear you miss him and time passed before you knew it. Also that hearing his voice would have just made you that much more upset, so that is also another reason you did not call as of yet. Yes he does not have a phone but I am in my early 20s and before we ALL had cellphones lol we would call what was called the house phone lol Try and do that too? He may feel like you aren't making an effort. Does your friend have a computer because cell phones me and my friends would talk on AIM. Download it for free and make up a screen name. : )
