I think it can be used in various ways to improve people's lifes in certain areas. I don't think the whole circus act hypnosis kind serves any purpose though. I hate circuses as it is anyway.

And to answer your question, I wouldn't use it on people I have a social relation with. Simply because it is probably not possible to put someone under hypnosis in a random situation, those things are being well controlled in every aspect. I think it would be kind of unethical too, manipulating people beyond their own control. But once again, that's not really possible if the person himself doesn't want to participate I think.

I like to manipulate people in the normal, intelligent verbal way. That works for me.
