^I love you because you're the only person I don't hate that
  much" - THIS needs to go on T-shirts, Hallmark Cards. It's a
  piece of art created by http://budy92.deviantart.com/ who came
  up with the phrase, although I've heard a similar sentiment. Had
  a friend who described our friendship like this years ago,

  "I hate everybody. Our friendship is based on hate. I just hate
  you less than everybody else."^
