I too want to forgo the exchange of gifts, though not just on all typical occassions such as XMas and Birthdays but also extend that to the fringe consumer-based holidays such as Valentine's Day, Sweetest Day, Mothers Day, and Fathers Day. Pretty much anything that is engrained by society. I'd rather do something nice because you want to, not because you're told you should.
The only exception is celebrations for young children. They should have fun on XMas and their Birthday.
