Hah. I'm ADHD and I used to be terrible about remembering people's names -- like, their names didn't even register and I couldn't tell you what it was 30 seconds later. It wasn't that I didn't care about the person, it was just that their name would never stick. Anyway, I finally made enough people feel bad and embarrassed myself enough that I started compensating and made a point to remember basically everybody's name that I met. The change was really surprising, people notice that sort of thing and they make an effort to return the same kind of energy. My general attitude about people since then has become a lot more positive because I realized that overall, most people really don't need a whole lot of impetus to show their better side, and it's not like it costs me anything to treat somebody with a little more consideration.

I remember the book saying something like "a person's name is the most beautiful sound in the world to them." The book may say to say their name back to them (I don't remember right now), but that's not what I took away from it. It reminded me of when people would make fun of my name (first and/or last) or bring up someone famous who has the same first ("Donald Duck") or last name ("are you related Joan Rivers?"), or someone famous who sounds like my first and last name put together (Doc Rivers), and I never thought it was funny. When I see people make fun of other people's names, the recipient never seemed to enjoy it either.
