Quoting la vie est belle ♥:" Just curious, what are the signs?"
My cousin didnt talk until he was 5, just babbled. He also was always overly fixated with one thing at a time...like that topic is the only thing he would talk about. He is 21 and still like that. He is socially awkward and doesnt understand emotions that much ((like sarcasm.)) He will get frustrated if something changes, simple things, like the time of dinner. It can come off as "spoiled" if you don't know much about it. He wants things HIS way. However, he excels in schools and always maintained above a 3.5 or higher GPA, even in college. He also has his first real girlfriend this year, which is awesome!
