I once saw a guy crying (with tears) out loud at Lahore Airport. He had just returned from Saudi Arabia with his wife. According to him, he spent 30 years of his life doing manual labor in Saudia trying to ‘provide for’ his family back in Pakistan. He has three sons well settled in Pakistan and none of them is willing to come to the airport to pick him up or (worse) keep him for a few days in ‘their’ house.
