So you want a mindless drone for your daughter. What a shame. I'll bet you also want them to do exactly as government says and "conform" as they walk him, her and their kids into more senseless wars.
Blind conformity is one of the most dangerous behaviors a society could exhibit.
Caring about what other people think of you leads to things like joining the KKK, stockpiling guns and killing six million Jews. It's religious think.
See, me, for my daughter, I'd be proud if she married someone who suggested they take the $30,000 he would have spent on a dumb diamond ring and try their hand at starting a business. Even from failure they would grow and learn.
There is no learning from in buying a diamond ring. It does not prepare you for life in any imaginable way. It does not prepare you for economic difficulties, medical problems or to develop a good sense on financial matters. It's just plain dumb.
