keep on thinking about this

we're all bound by the things we're used to. she assumes everyone has as much money as she does, i assume everyone had an education as thorough and deep as mine. she assumes everyone spends their free time in the same exact way, watching the same things, in their bedroom. another one thinks it's perfectly common to have a family member in prison. everyone is shocked by the revelation that none of us are like each other, that while everyone we've known up to this point was exactly like us, none of these new people are anything like it. how to deal?
