I have a really interesting story about Santa Claus. When I was 14, I was staying home alone on Christmas Eve. My family lived basically on our own and away from any family members. We moved where we were because both my parents despised my grandma on my dad's side, (long history of conflict there.) Anyway, there is no way relatives made a surprise visit around 4 A.M. in the morning, and my parents were several states away for a family emergency. I hadn't wanted to go and preferred to be home alone. All of this information is me explaining and proving that there is no one that I know, who could have been in my house at the time.
I got up to use the bathroom around 4 A.M., and was more or less half asleep, I know this because I went into the wrong bathroom the first time, (my usual one was being repaired due to leakage so I had to use my parent's bathroom on the other side of the house.). As I was returning to my room, I saw some dude bent over in front of the Christmas tree holding a small sack, I guess a rucksack, it was brown is all I know, and in my sleep-addled mind, I assumed it was my dad. The guy was wearing red, and he had my dad's general thin frame so I didn't question it. I went back to bed.
I woke up in the morning at around 10 A.M., and promptly freaked the fuck out when the memory returned. My parents were nowhere near home, not even in the same state. Went to my Christmas tree, and found 2 wrapped gifts, though they were unmarked so I have no idea who they were for or who they were from. I remember the guy was wearing a long dark red coat too. But not obese like Santa is supposed to be.
So, I got visited by the Skinny Santa when I was 14. My parents lost their shit when I told them. To this day, no clue who that was. I got to keep the gifts though.
