Reinhardt,

IMHO: Never mind where he was seated; he's a big boy and can fend for himself if he chooses. However, when he next comes in, speak to him and politely listen to him. Vet or not, he's an "elder" in life and if his mind is still sharp, would probably enjoy chatting with a young man such as yourself. Heck, perhaps he has fascinating stories to tell - and probably not about WWII. None of my relatives who fought in WWII will discuss much about it, which I believe I understand. Just not polite conversation and besides, I wasn't there.

<shrug> He may be a bore or he may be very interesting, but it would be nice of you to personally take note of him.

Kind of you to notice the gentleman in the first place.

Tom
