Yeah, your judging this without any information. He might have had buddies watching him, he might have been exhausted or just been chewed out by someone, and couldn't write in much detail. Look for patterns, not individual cirstances. If he is cold and distant for awhile, on the phone and on the computer, then you might have a problem. It's understandable, though, 'cause he's gone and you miss him - so of course, your going to glom on to every word.
