“If I turn on the light on Shabbos for an elderly Jew, and make him feel good, have I done a chesed?”

I agree with the sentiment that it is strange (i am being nice) that the shver “needs to see” a watch on his wrist, especially on the night of his daughters wedding. I agree that it is strange that this guy is more worried about the watch than his injuries (if I was the kallah i would seriously consider breaking up, what if she dropped his fancy esrog box and badly dented it, is he going to hit her?).
