I don't have time or energy to deal with a sub that is intentionally belligerent or TRYING to piss me off. My subs do not need to go out of their way to give me a REASON to punish them. In fact I have dropped on before because she was just a pain in the ass on a daily basis and was attempting to demand too much attention for attention's sake.
I want my subs to have a backbone in day to day like as I see the lack thereof as being a major problem in many people's lives, I want her to stand up for herself at work or if a friend attempts to take advantage of her for instance. The punishment she receives is for NOT doing so or for making poor choices in her day to day life.
