I came across this headline from Shine.Yahoo.com and SELF magazine. My personal opinion is: The reason we're unhappy with anything is that we have expectations of how things should be, and we're disappointed when those expectations are not met. Be honest: the things that make you angry are the things that don't work the way they're supposed to, or the people that don't do or act the way you thought they would. But that philosophy doesn't fill a magazine article. This article is well done by Jenny Everett.
