Your clearly bringing up Monster Truck well for him to be that creative and also to have the confidence and independence to think of and grab the Bungee cord,

many kids I see these days a) wouldnt be out helping, b) would be grumbling if out helping and C0 if asked to go get something would take there time but only return with what was asked for or come back with nothing forgetting what they were asked to get

so Cheers for doing a great job of parenting
