I'm surprised nobody has mentioned a rather important one: war.
Certainly makes it easier when it comes to children. If both parents have different surnames, which one is used for the children? Double-barrel? First child mum's, second child dad's, third child.... lol Although, when there's a divorce I think it's fair to say that the children often go with the mum, so perhaps it would be better for the guy to take the woman's surname? A bit of a negative outlook though I guess.
Apart from 1314Feeling guilty about what your country did hundreds of years ago.
Because it's an anachronism dating back to when wives were considered to be the property of the husband.
If you did away with those three war might die a natural death?You'll need to do away with many other things; religion, greed and corruption (to name a few) first. The list will be long . . .
Now why did you have to mention that mean-spirited, wart-faced, traitor?The Royal Family.
I live in the birthplace of Oliver Cromwell, ensures we never get royal visits.
Yes!!! COME ON RANGERS!!!!
