Consequences...

She does A
You do B

You don't threaten or talk about it, you just do it.

This is why people stop their car at red lights ENT... they know there will be consequences if they don't. They don't negotiate with the light, they either stop the car or they plow through and accept the consequences.

What are YOU prepared to DO if she doen'st stop?

If she doesn't stop (etiher by breaking a promise TO STOP and you catch her, or by outright refusing and you catch her ) you bring consequences down on her

No talk, you just DO IT.

She will learn that when she

Takes an ACTION
You will take an equal and consequential REACTION

There will be no talk, no begging, no complaints, you are just prepared to ACT if SHE DOES
