sometimes, parents have concern.
they have more life experience than you.
therefore, they may know that you two may not be happy after
marriage.
for me, listen to them.. see whether their reasons are ok.
i think that it makes sense for parents to object if you are about
to marry a rich lady. Sometimes, different background can almost
guarantee a unhappy marriage.
of course, if i were the parents, i will keep quiet. nowadays, guys
change girlfriend once a year. i only concern when they want to get
married.
