Rachel's little sister is three years old and leaves her toys all over the house. Rachel's dad asked her to help pick up the toys and put them away, but Rachel said she didn't make the mess and didn't understand why she has to help clean it. This caused friction between Rachel and her dad. What is the best strategy to help Rachel live above the line?

The best thing she can do is 1: Start showing her little sister how to pick up and teach her to get one toy out at a time. If this doesn't work she needs to sit down with her dad and explain to him that Rachel's little sister is plenty old enough to be cleaning up her toys so the responsibility doesn't always fall on Rachel...

Explanation:

(And if that doesn't work start throwing every single toy she see's on the floor in the trash) JK JK don't actually do that!!! Just an idea

i think the life is invaluable.

you can also say immeasurable.
