Not Engaging

What are some ways I can disengage from toxic behavior.

Walk away.
Roll up the window.
Take a walk in the opposite direction.
Get in the car and drive off.
Go to the bathroom, for a long time.
Mow the lawn.
Water the grass.
Sweep the porch.
Go to a nursery.
Go to the grocery store.

What are comments that don't escalate toxic behavior.

Hmm...
You may be right.
That's one way to look at it.
Let talk later.
I don't want to talk right now.
I need to think.
