I've said it once and I'll say it again, woe to the newly married woman who has, for years, have gotten so used to her surname only to find that a single (wedding) day, will change this familiarity forever.
I have to admit, it was not easy for me to adapt to a new surname, due mainly for professional reasons. Throughout my profession career, I have been known by my maiden name and to have to inform all my contacts of the change was, well, too tiresome. And so I decided to go the hypenated route and I eventually ended up with 2 surnames. Such was the compromise! =)
