I have friends who LOVE to decorate!
And grandkids that LOVE to open presents.
My favorite part of Christmas is when the family gathers and we sing "12 Days of Christmas." I just get the biggest charge out of accompanying on piano and assigning everyone their own "day" to sing about.
They HATE it! They whine and complain, so I have to really cajole, but most years we get'er done.
One year we improvised with my daughters boy-"friends." There were three that showed up unannounced while she was out with another boy. None of them would leave until she returned, so we sang!
What's YOUR favorite Christmas activity?
