I think, at this point, my favorite holiday would be Christmas and the surrounding holiday season. I mean, presents, festive spirit, feasts? It's a whole party season.
My favourite holiday is Carnival. A series of days celebrating festive clothing, fun activities with friends and joyous partying....
I'm only joking, Dutch carnival is about dressing as stupid as possible and getting drunk with your mates for about a week.
I don't really celebrate anything anymore. But I used to love thanksgiving with my dad. Now I just stay home and do nothing.
I personally like Christmas, It gets friends and family together to make lasting memories.
