marriage is 'ibadah. that by itself, means that (because its the nature of ibadah):
1. there's hardship involved
2. you have to do it for the sake of Allah. making your spouse happy will please Allah, n its 'ibadah.
3. men can sit and argue, have a disagreement. but after that, "what do you want from tim hortons?" women, once they argue, they become like palestine n yahud! need peace treaties, n all that. (LOL!)

for sisters:
1. marriage is 'ibadah.
2. your husband is nothing but a big baby. treat your husband like a baby (extreme care, pay attention, etc).
