I certainly hope Randy is not on a feeding tube very long if it upsets him to see other people eat.  Trust me, it's a self-defeating attitude.  It's true everyone is different, and I would have felt guilty if my loved ones and family didn't eat around me.  As I posted above, social situations and family reunions always involve food - the sooner Randy gets used to it, the better IMO.  
The point about cooking smells is an excellent one as they did make me nauseous at first.   Now however I savor the smell of food as I won't be eating it.
Finally, games are indeed good.   Randy is lucky to have such a caring sister who worries about him.  Love is something Cancer can't take from us unless we let it.
