I went to show the woman the receipt to prove we paid for these as we walked out of the store.
With a smile: "Oh Dear, I've been watching. We all know you paid for these."
And in another effort to recreate my own childhood, I tell the boys: "Go away. Get on your new bikes and go away. Go to the park. You can handle this, can't you?"
And they are coaxed out of the house and on to the bikes. The huge world in front of them, permission to cross that big street and go to the park, the forest, wherever their little legs take them.
Failure: They return after half a hour, with full tales of their adventures. Super excited, and back within 30 minutes.
Weren't they supposed to go away for hours?
