First, you need to have a fight with your daughter(s). If you don’t have a daughter, a son will do. If you have both (or a few of each), choose (or fall into) any combination of your kids to fight with. Typically, you won’t have to do too much here, fights with kids seem to materialize out of thin air in an unexpected fashion.
After the fight, fume a little (a lot). Let both sides get ready for peace.
Then serve lemon drops as a peace offering.
