A non-standard curse invoked by parents on their children. Said curse cannot be lifted-- only passed on to the next generation. It goes:
"I hope your children grow up to be JUST LIKE YOU!"
Statistically, this curse has shown itself to be effective.
Examples of the parental curse in action can be found in most any parent that became exasperated with the behavior of their kids, especially when they realize they were that way when they were younger.
