How did it effect you? I put this in this section, because I get the impression this kind of thing would have matterd more to a lot of NF children, and were maybe late on the truth?
I was older than seemingly everybody else I knew. I was really upset, and it took away the magic of Christmas for me. I was so convinced he was real that I swear I saw him in the sky! It was obviously my imagination, but it was so vivid! The funny thing is, I was half scared of him. I wasn't really scared of him, but more so the idea of seeing him. I wanted to keep him in my head instead, because I thought it'd be scary actually seeing him (I dunno)
It was my half sister that told me. She didn't actually tell me, but she said it infront of me, and her kid that was a couple of years younger than me. She said something like "we have to pretend he's real for your little brother" to her other son. I was like "..........*shakes head*.... *heart breaks*" I didn't say anything, but inside I was like "that can't be true, he is real!". I also was upset that people lied to me about it! I tried to believe it, but I couldn't from then on, so I just carried on believing in other things, like my stuffed toys coming to life when I'm asleep. (I'm not making this stuff up.)
Bah, Christmas has never been the same since...
ETA: I wonder if having an INFJ mother (my only stable parent) had an impact? She was dead set on keeping me believing in him for as long as I could. She said it isn't as magical when you don't believe in him. She even still put out food and drink for him, and Rudolph a few years ago, and I'm 21! When I was like "..........why are you doing that?" she was just like "It's for Santa and Rudolph!" lmao, bless her.....strange woman!
