re: Women not changing last name after marriage

Socially she is "Mrs. crispyUGA", but she kept her last name for business reasons. We married relatively late, we both had established careers that we are very committed to, and we don't want kids. I have no problem with her keeping her last name. I don't care, but it sits uneasy with my parents and, actually, with some of her family. They're also uneasy about us not having kids, though.
