I don't know about you friends, but sometimes you need to have a waive off. You know the drill, you stand at the edge of the lap and you size up your sweet spot.
On Mom, for me, that can be a lay across the lap or it can be the other direction, between the lumpy tender parts. Both have their advantages, and I can literally go either way.
So sometimes I sit on the sidelines and determine which way I want to go. I may be swayed by the "pat-pat" of the hands trying to direct me, or not. I make my choice and I enter the lap. I enjoy a light petting, but it can be distracting and can cause an immediate mission abort (especially if she tries to get handsy on a floof knot).
Sometimes I do a couple of turns, and then things seem off, and there is a waive off. This can take place multiple times over the course of a half hour. It's got to feel right, and someone complaining about "settling in" or "Cod! Don't step on those" doesn't help.
I know you understand.
