Someone asked me what my favorite holiday was and all my brain had was a flashing 404 - Data Not Found code.
I don't have happy holiday memories from my childhood. The happiest one was when I was six and got a microscope and a sled at the same holiday, but it still a traumatic memory.
My memories from adulthood are shaped by those early memories. I'm sure there must have been some good holidays, but the majority of them were dominated by tragedy, abuse, or other trauma. I've had better experiences as an adult, but the shadow remains.
