that's a good point. I guess that's why I don't let it worry me too much if someone starts to wind me up - I can always make the excuse, how do I know they aren't just trying to wind me up on purpose? which btw is something my family would do, so I am susceptible to it, and maybe overly suspicious of it. so I try to remember the guidelines and just take care of myself. OTOH, as long as you're not getting caught up in something? i've been in experiments, and they usually need to be much more controlled than this to have any validity. So there wouldn't really be a point. Cuz how would you know that the person you think you're taking notes on, isn't taking YOU for a ride? So, I wouldn't worry.
