My mom always ribs her best friend's husband who was a Marine...says "You can always tell a Marine! You just can't tell 'em much!"
Poor guy...in just the few years we've been here, he has lost it to Alzheimers. My dad took him golfing almost every day, until he got to where he just didn't even know where he was, just a few weeks ago...now he goes to an adult daycare center a couple of times a week. He's not too angry yet...but it's coming.
