I am probably a little too young to feel this way, at 21, but I feel like a vampire. I am assuming a lot of autistic people may get this feeling...
A day ago, a sister of my aunt ask my sister if I was her little sister, and then later in the conversation she was surprise to find out I (we) live on our own. Let alone I bought my own home. So if she thought my sister was at oldest 19, then she must had thought I was like 16-17.... At a job interview, they ask if I was at least 18, even after knowing I graduate high school like a few years ago, with years of working experience. I am ask ID at like a pawn shop.
Then today I visit my old neighborhood, and I notice all my neighbors are old and looking like adults. And I practically remain the same (if not look younger than I do back then).
it's kind of freaky, since I feel like I am frozen in time, but I also maintain an anti-aging regime.
