This girl got the perfect revenge on her ex when he asked for his money back

Everyone needs a hero.

Someone to look up to. Someone to take after. Someone whose actions inspire the rest of us to be bigger, brighter, bolder. Today, that someone is a young woman named Harriet.

Harriet appears to have been the unfortunate victim of cheating. Many of us have been there, many of us know the pain it causes. It's one of the worst things you can do in a relationship, and those who have been hurt have no doubt fantasised about taking revenge.

Fortunately for Harriet, she was gifted the opportunity to do just that.

The couple had plans to go and see Justin Bieber, but Dan's alleged indiscretion has cost them this wonderful evening.

Dan needs the money, and Harriet agrees to pay him back. But Dan did a bad thing, and bad things must be punished.

Harriet hasn't explicitly stated the sum that she 'owes' Dan, but she alluded to the fact that it would take 17 years to pay him back. A quick bit of maths reveals that the amount is around the £62 mark.

And to prove she wasn't joking...

Once she posted the burn, the internet burst into a figurative round of applause

Harriet, we salute you
