Things not to do while driving.....

This afternoon when coming back from the grocery store, my wife and I were talking.
She paused for a minute to reply to a message on her phone.
I patiently waited for her to continue speaking.
In the brief moment before she responded.....
I had this overwhelming, uncontrollable urge to give her a wet willie.....
Apparently, I am not supposed to do that... And she is allowed to retaliate while I am driving.
I think my arm is bruised....
