re: Do you personally know anyone who has legally changed their name?

Yes. I know two people who did that. One said it was because of an abusive relationship with his father, so he didn't want his father's name. The other was because his twin brother was fricking up his life (so this guy said).

Both people are...interesting. I'm convinced that one of them is a sociopath, while the other is just a passive aggressive little bitch.
