I spend most of the late morning and early afternoon at my grandma's. My dad's side is huge and we all pile into her house and eat way too much
Then I come back home, change into comfortable pants and lounge around for a bit and then go to my brother's house to exchange presents. I have like 4 or 5 different Christmases every year but Grandma's house never changes. That's always a must.
How about you?
