I enjoy...

...when women change their names when they get married. Don't know why, but hyphenated names kill me. maybe cause i grew up w/ a stepmother who already had a daughter and when she married my father, didnt wanna change her last name from her other married name, which was also my stepsisters last name. so she hyphenated, and sometime shortly before my sister married (and took her husbands name) my mom dropped the old married name and kept ours. I think that's why in my mind, i believe keeping your old name is to somewhat 'reject' your new life, to have one foot over the threshold and the other firmly planted on the old trusty doormat.
not that im in love with my boyfriend's last name. it's very two-syllable english/scottish/bland. mine is three syllable sing-songy to match my three syllable unique first name which when people hear it requires them to hold their breath for a satisfying closer. my last name, all but cinches the deal like a note to end a song. Like the familiar trumpets at the end of a mariachi song. You expect it, you welcome it, you love it.
Of course it'll be difficult to give up my last name one day. So I've long ago accepted that I will throw out my middle name (as much as I adore it), shove over my last name in its place, and be happy that I got away with a non-hyphenated name change. Is that bending the rules? Probably. I definitely see nothing wrong with hanging onto the name and hiding it with an initial. I'm Latin, people, to adopt an English name will be like lobbing off my arm and replacing it with a prosthetic. And they don't make brown prosthetics. Well maybe they do, but no doubt it just wouldn't feel the same.
But I do love this man, and should he become my husband some day, I would be honored to take his name and scootch my own to the backseat. A silent G. to anchor my name but allow the first and new last name to be my identity. No one will even notice. It can be our little secret.
