I am happy that you can do what ever pleases you. I, personally, took my hubby's last name. Although, it is long, and difficult to pronounce, I am kind of a romantic at heart, and I guess old fashioned.... I've always had the day dreams of being "Mrs. D-So&So".... even though I do love my maiden name.... also, it was important to my hubby... I thought about keeping my maiden name (my father is the only boy & had all girls, so the "family" name would die with him), and my hubby would be ok with it, but he wanted everyone to know that I was his wife.... not in a property/controlling way, in a "proud to be married to this wonderful person" way. In our neighborhood, hubby's last name is well-known, it is an old-school Italian last name, with lots of stories and history to it. And even now, if I go in to pick up my pictures and say my last name, someone will hear and say "D-So&So? Are you related to Tom D-So&So?" I'm always afraid to say yes (my hubby was a mischievious little devil when he was younger)....
However, being a child of divorced and re-married parents, it was always a pain in the butt at school. My mom had her 2nd husband's last name, and would sign our papers Sherry Something, while my name was Heather Help. Papers were misplaced cause they would file under S instead of H, and the school would not know who the permission slip was signed for etc. One time they wouldn't let her take us out of school early cause her ID said Sherry Something, and we were all Help's kids. Plus the embarassment of having to explain at 9 yrs old why your mom's name was different than yours was never fun. This is why my sister (who had a child out of wed-lock) gave her son, her last name (also my fathers last name which only makes him beam with joy everytime he hears it!). It also makes life easier with Dr's appts for kids too, and for insurance purposes for the child to have the same last name as the primary caregiver when parents are un-married. And so I imagine, that if I did NOT want to take my hubby's last name, and I was the one taking care of school/drs appts/etc I would probably want my children to have my name, even if it is my maiden name.... although, I don't know how the father of the children would feel about it, I guess the children could take their fathers name when they were out of school, or at an age where they could choose.
I do know someone who hated, hated, hated their maiden name (Failor) because of being picked on as a child, and hated, hated, hated, their husbands last name (Urin, pronounced errrrrin, but everyone says urine), so she took both names and made 1. She took the Lor from Failor, and the rin from Urin, and made Lorrin.... and that is her last name, even though her husbands is still Urin.
So, I am thankful for the right to choose.... because while I love having my hubby's last name, I love that my nephew does not have his father's last name, and that my sister was able to make that decision!
