write him letters and call his cell phone and leave him voicemails, and if he has a myspace or facebook or what ever leave him lots of messages. A few of my boys are locked or have been and even though they can't listen to the voicemails while they're there, they can hear them when they get out and are usually touched (but won't admit it). I'm sorry about your friend, hon. That really sucks, but support him as much as you can. <3
