When I was a kid, my dad always had to work a half day on Christmas Eve. He would drop my mom, brother, and me at my grandmas house in Berwyn about 6 in the morning, then when he got off at noon he would join us. My aunts, uncles, and cousins would all be there. My one bachelor uncle would always insist on picking up the tree and decorate it that day, which was a challenge, those old lights, if one was loose or burned out the whole string wouldn’t work, so that always took time. We would have dinner, open presents, then leave for my other grandparents house in Mokena to open presents there. ( I now live a few houses away from their old house).
On Christmas Day we opened presents, then the entire family came to our house for dinner. This all ended when I was 15, my mom died that year on Christmas Eve.
