I got that animal whisperer autism

I (nb17) moved in with my aunt about two years ago now, and at first this guy did not like me, but he's definitely gotten attached, like I get home from school he's waiting by the door or at the window for me, he's not usually very vocal yet I've been the person he's meowed the most at, and he's very much one you can figure out due to body language so more recently I've started telling him "if you want attention you're gonna have to come up here." so I pat the spot do the little 'phst' thing and he comes right too me. Like he doesn't do this to anyone else!
