I was cutting down trees. Evan kept running by and grabbing every piece of wood the moment it hit the ground.
Not his wood. Mine. The stuff I just cut and was planning to use.
He wasn't being malicious. He just saw it, it was there, and he needed wood. So he grabbed it and ran.
I called him a wood thief. He said 'How dare?' and thought it was funny. Then he moved on.
This happens in real life too. Kids don't naturally have a concept of 'your stuff vs my stuff' when it comes to household resources. Especially in a co-op situation where the instinct is to contribute and take as needed.
It's not a bad instinct. It's just a thing you work out together. Where's the line between yours and ours?
What's the household resource your kid treats as shared property without thinking twice?
