Not Married yet but this question always pops up in my mind too..

LADIES AND GENTLEMEN ON QL when u read the answer read it from all the angles , as in if u were a mother /wife or a child .

Answer is..

know your duty towards each of them and priortize it accordingly...Show them equal importance....

i m sure a Good mother will always like it if you take your wife for a candle light dinner..

I am also confident the a good wife would be proud if you bought a daimond ring for your mom on her Bday..

What say guys....

Spread equal love and attention...?? correct me if i m wrong
