The Mr had this experience with Mikah and Lukas yesterday when he picked them up from the babysitter.
He told me that they had made it the usual block before the fighting started. I guess that Lukas took off one of his boots and started hitting Mikah with it. For some reason Mikah took offence to this and he started kicking Lukas. Lukas started crying. Mikah saw that Lukas was distracted, so he grabbed the boot Lukas was using.
By this point both boys were wailing, and the Mr said he figured the boys should have to work some of this stuff out for themselves and this was a good opportunity to let them try (plus we get damn tired of refereeing). It's a good thing that he kept quiet or else this conversation might not have taken place.
Lukas: Give me my boot back!
Mikah: You have to say your sorry and apologize.
Lukas (says in a monotone voice): Fine. I'm. sorry.
Mikah: That's not sorry enough.
Lukas (sighs, and says in an extremely exasperated tone) I'm sorry and I love you?
Mikah: More sorry.
Lukas: I'm sorry, and I love you, and you're beautiful?
~there is silence for a moment~
Mikah: ... did you mean awesome?
Lukas: yeah... awesome.
This seemed to be acceptable and Mikah gave Lukas back his boot. A minute later the hitting, kicking and crying recommenced. Don't feel sorry for the Mr though, he laughed the rest of the way home.
