Consistancy, when in dealing with any sub, seems to be important. After all, how can a sub trust a Dom, who changes His desires constantly, drops orders almost every other day, creates new "standing" orders, then forgets all about them after a few days, or few hours?
For example, one second, this sub is required to perform a specific duty, or behaviour, which is immediately punishable if not carried out. The next day, He doesn't even remember this new rule himself, and it is never used again.
My question, I guess, is how do you help/solve a lazy-thinking Dom? Who creates new orders on a whim, then forgets about them, or does not require/reinforce them after being obeyed once or twice?
