The 4 cardinal rules by Uncle Sam

Uncle Sam believes for a married couple to be perfectly happy together, they must have the following in common:

• Religion
• Food Habits
• Mother Tongue
• Family support

The sane Karizma agrees. It is kinda hard to imagine a perfectly strict vegetarian married to a carnivore who just can't do without meat .. or a staunch Muslim married to the devout Hindu Brahmin .. but then, there's the heart factor .. and what about all the 'opposites attract' theories?
