Agreed. The change doesn't have to be quite as profound - and it's up to other people to choose how to react and proceed. Different quantitatively but I think

Agreed. The change doesn't have to be quite as profound - and it's up to other people to choose how to react and proceed. Different quantitatively but I think similar qualitatively, my best friend (despite my warning) attended a high-intensity motivational/NLP weekend seminar a few years back. It is no exaggeration that he came out a completely different person, in the sense that the stimuli/response has radically changed. He was more emotional, open, intense, etc. My reaction initially was confused and highly negative; and eventually settled down on "The person I knew is in some ways gone; but let's give this new person a chance and see how we get along". Others, erm... did not react as positively :P
