I think they should at least have the decency to set up separate funds for their kids to pay for name changes on all legal documents if that's what they decide to do

Honestly seeing Big Daddy as a kid, this has always been deeply ingrained in me. I have a very common first name, and as a result have such a detachment to it that I don't even care what name people use for me (so long as it's respectful).

But I always thought it was so bizarre that you're legally stuck with a name you didn't choose for 18 years. Let kids pick their own name that's used for school and whatnot, and let them change it (I dunno, maybe once a year?). And then when they're 18 they can make it permanent.
