It really doesn't.
It just frustrates me.
We're trying to raise a polite little guy, aware of his impact on others. And some days it just feels so fruitless.
But then I remember that his best little friend, who has always been such a sweet, caring, well-behaved little guy ... he does the sorry thing too. Like every other word out of their mouths some days is "sorry." Even when they haven't done anything. Like some kind of prophylactic against future bad behaviour.
I hope this is just a phase
