A way to show sympathy and apologize to subjects.

In interactions, you'd be able to apologize to subjects, as it is easy to make a mistake, such as miss-tapping "bite" rather than "suck," or accidentally overstimulating a subject. It'd be a quick way to ease a subjects anger, although apologizing would be a sign of weakness, therefore (dominant/switch) subjects would become more dominant.

Also, an interaction to ask a subject if you are going too fast/hard would be nice.
