it sounds like i good job for him...being a courier also will get him out of a strict office environment too which might work out well.
His last job before the one he lost after two weeks, was driving delivery trucks for AutoZone. He liked that, but the hours weren't great, nor the pay, and no benefits. When I told his younger brother it looked like he was gonna get this new job, he said, "It's perfect for him. He can drive, listen to his stereo, and not be around people so much. For him that's a GOOD thing."
I hope someday he gets a little more comfortable around other people, but hey, he is who he is, and the whole secret of being happy with your work is finding something that's a good fit for you, personally. I've been VERY blessed in that respect--it's part of what makes the prospect of retiring from my present job kinda unsettling. Hard to imagine anything else that would "fit" as well.
Never know, though. Maybe I'll love the hell out of my new life.
