"But what America did was a basic human obligation. It is the obligation of every person born in a safer room to open the door when someone in danger knocks. It is your duty to answer us, even if we don’t give you sugary success stories. Even if we remain a bunch of ordinary Iranians, sometimes bitter or confused. Even if the country gets overcrowded and you have to give up your luxuries, and we set up ugly little lives around the corner, marring your view. If we need a lot of help and local services, if your taxes rise and your street begins to look and feel strange and everything smells like turmeric and tamarind paste, and your favourite shop is replaced by a halal butcher, your schoolyard chatter becoming ching-chongese and phlegmy “kh”s and “gh”s, and even if, after all that, we don’t spend the rest of our days in grateful ecstasy, atoning for our need."
