This gave me an idea.
So I went and got a couple of old paintbrushes, and a watering can.
Now we could paint on the ground.
Didn't look like much, since the paintings kept disappearing, but very satisfying...
Then, my daughter started drawing on the wet concrete with chalk. Which made the colors really nice.
This turned into an afternoon of painting, adding chalk, painting, adding chalk...
We did some yard work, too, in which tools were moved around by people who were smaller than they were... which brings me to:
Is this possibly the worst place you've ever seen anyone leave a shovel?
Okay so maybe some pointers on safety are needed.
