I have learn to be more accepting of people who change their surname when they marry. Personally, I see it as an archaic and unecessary practice. Why on earth would you want to change your name just because you've married someone? But I should remember that many people wouldn't have it any other way, perhaps seeing it as an honour to take the name of the person they love. It can even be a way to ditch an unwanted maiden name, or symbolise a fresh start in life.
[I mean no offence to those of you with married names. I really am chiding myself here, not questioning your choice.]
