I was pretty lucky when I was little, as the cult hadn't taken hold of the family yet so we still got to celebrate Valentine's Day, Easter, birthdays, Mother's Day, Father's Day, Halloween, Thanksgiving, and Christmas. Up until I was 8, we used to go trick or treating. Then some wack job in the neighbourhood started poisoning and sticking pins in the candy so Mom said no more trick or treating -- she would just give us a bag of candy. I was cool with that!
Mom used to decorate for Christmas. But she became allergic to the trees so she went with a treasure hunt for us. It was quite fun, actually! Once we grew up and moved out, our parents decided to become baptized JWs. That's when things started really dropping off from a holiday celebration perspective. So me and my bro kept up with Christmas. Thanksgiving was ok still for some reason. As for birthdays, well, they were still kinda happening.
A lot of my family is gone now so holiday celebrations are a bit meagre. Oh well, I am going to the movies this evening.
