The problem is we expect too much. Expect to be understood without saying a thing, expect to be given what we want without asking for it, expect to have the other person think of us before themselves, expect, expect and then expect some more. The truth is, ALL that comes out of this tireless anticipation is, lets face it, NOTHING.
"As soon as you stop wanting something, you get it" said Andy Warhol. You know what? He was absolutely right.
