What are some examples in the isolation of individuals?

“I’m antisocial, they say. I don’t mix. It’s so strange. I’m very social indeed. It all depends on what you mean by social, doesn’t it? Social to me means talking to you about things like this.” — Clarisse McClellan

“We have everything we need to be happy, but we aren’t happy. Something’s missing. I looked around. The only think I positively knew was gone was the books I’d burned in ten or twelve years. So I thought books might help.” — Montag
