grocery shopping = marriage life?

I accompanied my parents to grocery shopping today at the new Giant in Melaka. During the 1.5 hours time we pushed the trolley up down left right front and back of the supermarket; compared prices of the fish; admired the cut of the lamb shoulder; picked the reddest tomato; argued over vitagen and yakult; dicussed the benefits of oat & muesli; debated whether if wholemeal or multigrain bread contains more fibre; waited in line for peanut butter waffles; chose between arabian or columbian coffee beans; and met two of my parents’ couples friends who did almost exactly the same thing as us, except that they don’t have, within their near vincinity, an argumentative daughter who will sneakily slipped in her favourite vitagen into the trolley no matter what her mum says.

Makes me wonder, does happy grocery trips made up a harmonious marriage life?
