Aprilviolets, you are not alone. My parents kept giving me dolls, until I had a big basket full, though I rarely played with them. I once had a dollhouse and I remember a playmate and I once cut off the limbs of the dollhouse dolls in the course of imagining some traumatic situation : , even that didn't register with my parents as being "different". I thought my brothers had the neat toys and I was elated when their toy dinosaurs started being passed to me. At 48, I mentally still play with my childhood dinosaur collection -- guess I relate better to dinosaurs than people
Here's one of my quirks: I hate fingernails and toenails. Though I hate people with long fingernails to touch me with their stabbing implements, I mostly hate my own and keep both fingernails and toenails trimmed very short. Because they grow in thick and callused, I hate the sensation of the nails on my little toes against my shoes, so I go beyond trimming and remove as much of the nail on my little toes as I can without causing injury.
You folks are the first. I haven't even confessed this stuff to my therapist.
