You are all so wrong and insensitive to the needs of a honking driver in Karachi!. Shame on you. Have some sympathy for the people who spend endless days outside the home in a city that has NO CONCEPT of public bathrooms. I am gonna ask you next time you ate Nehari for lunch and are just trying to get back home JUST IN TIME for that explosion that’s building inside you while you wait for that riksha or tanga infront of you. Aur julti per tayle yeh k the horse infront of you is showing a mini version of Niagara Falls and proving Newton’s Law of gravity by dropping objects in a freefall motion. 
in pak...my cousins get on the free way and leave their hand on the horn for the whole trip..talk about smart.
