It's the letter nobody wants to receive from the social services department.
"You have been overpaid. We are, therefore, required to recover this amount."
"Oh God!" you think. "I didn't realise! Will I have to sell my house? I don't own a house! Why did I spend my house savings eating all that smashed avo on toast?"
Kerry King, a mother-of-two from Victoria, received this letter from Australia's social services department Centrelink, Mamamia reports.
But amusingly enough, the letter went on to say: "Our records show you have a debt of $0.02 and you have not made an arrangement to repay this debt.
"We would prefer to settle this matter without taking action."
That's right. The department sent this woman a big scary letter to inform her she had a whopping 2c debt to pay off.
Kerry, being the upstanding citizen she is, was not about to ignore it.
She sent the letter back to them paying her treacherous debt in full, in the form of cold hard cash.
Yep. That's an old 2c coin taped to the original letter - they were officially removed from circulation in 1992.
She even sent them a cheery "Merry Christmas" with an accompanying Santa smiley face.
"I was contemplating sending them a five cent piece and asking for the change," she joked to Mamamia.
