Peggy has long played a game with me where she would come between
my knees and I would give her a gentle squeeze, saying “gotcha”. Her
control of the game was very clear in such acts as putting her arm
between my legs as bait and in her squeezing my knees together when I
showed a reluctance to play. Today, a new development. Peggy
presented her toy “Bearhug” for squeezing. When I realized her
intention, I complied, but at her first presenting the bear I was
confused, thinking she wanted me to hug the bear, which I did. Peggy
was unhappy and taking the bear with one hand, she held it between
my knees and trying to close my knees with a hand on one she said
[gotcha].

What I see as interesting here is the fluid relation of our actions and the
control of them and the complete and partial changing of roles
between hugger and victim. (confer also P85) where this is
documented.)
