> Life pro tip: teach your children to do chores.

Before teaching your children to do chores: x hours per week for chores

After teaching your children to do chores: y hours per weeks to have annoying discussions with the child, and X hours per week cautioning the children to do the chores, and ensuring that your children do the chore properly. Here X > x.

Additional time for you: -((X-x)+y), where X>x and additionally y > 0.

I did a lot of chores growing up. Looking back, X>x was true for the first few months of each new chore; but X died down to zero as time went on.
