PS I think this is a fabulous thread starken. I also agree with BDSM_Tourguide's reply. The man clearly knows what he's doing. I especially like the suggestion where forgetfulness was mentioned.

My Mistress often assigns certain tasks and checks up to be sure they were done correctly and timely. At first I used a reminder program on my computer and on my cellphone (it has a scheduler). However, she frowned on that. She preferred the idea of me remembering on my own.

Well... I'm a forgetful little slut at times. I often miss a detail or three. It offers her ample opportunity to punish me in all sorts of delicious, horrible, sexy, humiliating, and frightening ways. It also allows me to feel useful. I know I'm doing things that she wants or perhaps even needs. Such usefulness seems to be at the core of my submissive nature.

Bah, I've gone off on a bit of a tangent. Basically, I wish to highly recommend "to do" lists that she may write down and check off later... but that you must only commit to memory. 'Tis great fun.
