For the Sibling Fight Over One Cup at Breakfast

Four lines you can say out loud tonight. Word for word. Free to save.

What to say

1. One thing each. If you both want the same one, neither of you gets it.

2. Wanting what your sister has isn’t greed, it’s how it works at your age.

3. The blue cup goes to whoever had it yesterday, so today it’s her turn.

4. Tomorrow is your turn, and I’ll say it out loud so she hears me.

When to use it

This is for the moment it actually goes wrong — not the calm version you rehearse in the car. Pick one line. Say it once. Then stop talking and wait three seconds. If they push back, repeat the same line, not a new one. Say the same thing for five nights before you decide it doesn't work.
