"We’ve all selected the wrong partners, all gotten hurt, and hopefully all moved on wiser for the experience. But there are those who, even in the face of constant disappointment, continue to believe that the intensity of their desire will be rewarded by an eventual jackpot of affection. And if that’s the slot machine you’re playing, friend, you’d better leave the casino ‘cause that one don’t pay out"

This is the reason why I would be disturbed by the people who would leave a comment on some Harley Quinn or Joker picture that I drew stating that their own relationship reminded them of the two characters. I would always try to reply in a way to see if they were okay, and for the most part it would be someone with the idea that The Joker and Harley were in a some sort of truly romantic relationship possibly due to fan-art or fan-fiction.

Harley’s original creators always painted a pretty clear picture of what their relationship was.

Seems the picture may have been repainted a few times, but I’ll always be a fan the original tales and what lessons I can take from them.
