canadian piggy bank

When you owe someone a sum of money, but instead of giving it to them directly you leave it in a hidden place where they are guaranteed to find it. The owed party will initially be angry due to not getting paid in person, and the owing party will have to respond with "I'm sorry" the next time they meet, like a true Canadian.
