Is this a poorly executed ‘come hither’ look, or a well executed strop? I’m pretty sure it’s a strop.
I’ve had to deal with a number of these over the years - the girl who feels the need to show defiance, or has a desire to rebel, or who just wants to play up because… well, because that’s what girls do sometimes. The strop that means you are going to have to work on them for a while to remind them who they are - and who you are.
As with so many things, physical violence is an excellent solution - it’s not hard to over-power them, and with this kind of mood something like a spanking is probably most effective as it’s a regressive gesture that regressive remedial action can be very effective against.
However, it can be more satisfying to use emotion to overcome the situation. If for no other reason than physical violence is often what they were looking for in the first place.
I find an effective way to deal with a strop is stillness - quiet disengagement and a steady gaze. Just wait. And watch. And prove that you cannot be provoked. Demonstrate, in essence, that no matter what they say, or what they do, or how they act, they cannot take control of the situation, they cannot make you do anything you do not choose to do. Of course, make a mental note of every slight, of every out of place word, every disrespectful gesture. But in my experience the one thing that a sub in a strop cannot bear is for her strop to be ignored. I’ve often seen it result in a sub breaking down in tears.
That’s the point to move - the point where they say they are sorry and will you please ‘come back’. Return, take complete control, apply punishment - and work through the entire mental list of things that were said and done wrongly.
Or maybe save a few items for next week when they think they’re in the clear.
