I think you can by feeling generous and buying gifts puts some people in a dilema..................maybe they already have a large amount of family and friends that they buy gifts for. Buy giving gifts then expecting one in return, is not what it should be about.
Im having non witness family over for xmas and have said NO PRESENTS. I just dont want it to start, worrying and looking for gifts to me is painful, id rather give something that catches my eye and I think they will enjoy, rather than HAVE to give at a particular time (children excepted)
Saying that I will be buying my DH a gift...............but everyone else NO !!
But then again maybe im horrible too
