Kwanzaa -- which is a cultural and social observance amongst African-Americans and has nothing to do with Christmas or any religious celebration -- is, in my opinion, a many splendored thing. It is inclusive, it has principles that are universal and because you can veer away from the hard and fast rules of it all any way you like (and yes, there are rules), it can also be a lot of fun.
Basically, you have to make the gifts that you give. Educational gifts are encouraged. What's important is that you give of yourself. The upshot of it all is, for those seven hectic days after Christmas when the rest of the world is running around buying more stuff, returning stuff for more stuff or breaking toys they just got, you are gathered together with your family, your friends who are your family and the ones who really matter, and you are focused on other things.
My first day of Kwanzaa was an unstoppable fountain of joy.
Onward and upward.
