I didn't really do something special. Where I live is a cold place during December, and as I'm not very into cold weather, and you know, the pandemic, I didn't go with my family to the valley because it is even colder than the city. I bought some "rancheritos" (a typical corn snack from "sabritas", "lays" in English) and watched "Fate zero", an anime that I'm watching right now. Alone but happy hahaha.
