That is all going to pay off BIGTIME, SRS. We have a coupla kids now long past that age, and it's been amazing how their ability to do that stuff serves them in life.
For one thing, it makes them the go-to person for their friends, and from that place they can actually help their friends in a million ways-- compare this to one kid who had only just learned to feel comfortable in the kitchen when he moved out, but serving his dad a steak dinner at Navy grad-time, WITH "vegetable matter" (OK, cold out of a can but it was THERE and he had actually bought it because he liked it).
