I've lived in African countries for about 15 years. Thought I couldn't manage usa again due to the loneliness. But Pittsburgh proved me wrong. After buying a house here, I immediately knew all the neighbors, they now have keys after like a few weeks. And random strangers pause on the sidewalk to offer to help me carry things. A jogger stopped to help me load my car. Hell, a drunk woman in pajamas staggering down the sidewalk at 11pm one night stopped and said she was so "rude" for not offering to help me carry my 4 grocery bags. I adore this city. My current team in Uganda, who are like my family (and are Ugandan), have decided it's the only place they'll "allow" me to live in the USA as it's the only one they've heard of that meets their criteria of a place where people take care of each other appropriately. I've travelled to or worked in maybe 60 different countries. Lived in 4 different countries and 5 states in the USA. Pittsburgh is a gem like none other.
