But I stand by my contention that adults giving gifts to other adults is, for the most part, just wrong.
When you are close to another adult and wish to give them something special, that's great but, in my opinion, that's what birthdays are for -- a time for a special gift to someone special. (Although, why wait for some arbitrary day? Just give a friend a gift if you want to, any time).
Chirstmas has become too commercial where you go deeply into debt, buying unwanted things for other adults you don't even know very well -- just because "it's expected". Now that's wrong.
Where there may be exceptions, there is nothing wrong with simply banning adult to adult gifting on Christmas. Trust me, pretty much every adult involved will be grateful. Instead, let it be a time of getting together for family and friends.
