People often treat happiness like the end all be all of life.
Which makes perfect sense since most are miserable.
More than they'll even admit to themselves.
Thus they seek to not feel awful all the time and see happiness as the answer.
Sadly they've not a clue how to get it.
@masternumber consider how backed up emotionally basically everyone is and conclude you don't need to hate someone. they already hate themselves more than you ever could.
What does it say about our society that so many people are hellbent on distracting themselves however they possibly can for as long as they possibly can?
