I think it feels good when a fellow bald man (those who shave their head, anyway) compliments you on the look. I've had that happen once a couple months ago, and I was glad that it was brought up for once not in a joking way, but rather seriously.
Often people will joke about my baldness and I take it in stride, but it does get old, so it's always good to hear something positive like, "Yeah man we're rockin it together!"
As for the UPS vs FedEx thing...I found that in my part of New England UPS was generally more reliable at standard ground deliveries, but if I needed something ASAP (overnight, next day, etc) FedEx was king. Does anybody here for for DHL? :-p haha.
