Disposable society?

Who gets their exercise by jumping to erroneous conclusions? I know I'm guilty of it. I also know that my sense of humor and what's appropriate gets me into lots of trouble sometimes, but most everyone I know realizes that's just a quirk of mine. Certainly not something that would constitute the severing of a friendship. At least not in my mind.
I read somewhere that we've become a disposable society and I suppose relationships of all sorts now fall into that category. Marriages, friendships, employers, family. When the going gets tough or someone misconstrues a comment, why has it become so ridiculously easy to just walk away?

Strange and pitifully sad.
