I kept my last name when I got married (How could I not? My initials spell a word, after all.) It seemed to blow the minds of some of my relatives, but in the almost three years I've been married, it hasn't caused any problems until today. I need my husband to go pick up a package for me, but since we have different last names, they might not let him pick it up.
I Blame The Patriarchy!
UPDATE: Apparently, DHL is happy to fight The Patriarchy, and let him pick up the package. Which is my new computer. With which I found out that f-words looks horrible on a bigger, better screen. I hope to have that fixed soon. Yikes!
