When I became Catholic I used to joke that it was because they had so many more holidays and feast days and that I was just doing it for the parties and celebrations. While it was technectly a joke, I really do enjoy all the excuses to celebrate.
I love throwing parties and celebrating even the smallest thing. Heck, once I even invented a holiday with my brother called Chronoheximatica! (That was a holiday that only lasted for one second on 01/02/03 04:05:06)
This is why I always tell William that Pinkie Pie from My Little Pony is my spirit animal.
Her special power is laughter and she loves to celebrate. She once threw a surprise party for any holiday she might have forgotten or didn't know about yet. That's so great!
So obviously when William say this Pinkie Pie with a Santa hat he knew he had to get it for me.
He knows I'm crazy, and he's ok with that.
