When I have a mother of an autistic child say, "My kid went to college because of your book, or one of your lectures," that makes me happy.
Cand o mama de copil autistic imi spune "Copilul meu a mers la facultate din cauza cartii dumneavoastra, sau din cauza uneia din prezentarile dumneavoastra", lucrul acela ma face fericita.
