Yeah, this really depends on several factors and the current
circumstances.
After our registration (not dinner ceremony), I moved in to my
spouse's place, because the real estate at mine was simply
insufficient to accommodate another person. And we had no home to
call our own yet. Personally I'm really quite easy about the
surname thingy; and I'm pretty sure the spouse's all right too, as
is her family. We don't have kids yet, but it's certainly not going
to be an issue of contention. Nor do I expect it to be something to
be raised at all; I mean, man has probably lived with such a
convention for hundreds of years...it's really quite a waste of
time to be even raising such an issue, isn't it?
Nevertheless, I think it's really a question of traditional minds
versus the contemporary one. No one's really right in this sense. I
don't know, but there might be one or two religions out there which
insist on the traditional mode of things.
It's a harmless thing.
