A Mother's Grand Advice

The rain was pouring heavily. A family of four stepped out of a coffee shop. The man held an umbrella for his wife while he asked his daughter the hold an umbrella for his mother. His daughter grudgingly takes the umbrella from her father's hand.

Daughter: Why can't you hold the umbrella for your mother instead?
Man: Because it's in my wedding vows, just like you said yesterday, to serve my wife.
Daughter: *Grumbles* Where got such thing!
Man: Got.
Daughter: Your mother, your obligation bah.
Wife: That's why don't have sons next time.
Daughter: Wha?? *How the hell to do that!*
Wife: *Points at husband* They'll be replicas just like that.

Few months back... Wife, husband and daughter were in the car...

Wife: Don't have sons next time.
Daughter: Wha?
Husband: *Grudgingly continues driving*
Wife: They spend more money on their girlfriends rather than their mothers. Waste of money.
Daughter: I already planned to be a spinster.

I am living testimony and I wonder how the hell as well.
