I never assumed I know you. Your words which you wrote, give an indication of who you are, as a person. By reacting to your unpleasant reply, I am the one with an ego?

All I asked is that you help children, instead of using them to amuse yourself - as your original post indicated you were doing. I had thought it was due to you not thinking of what could go wrong if a child thinks your so-called poison-filled toothpaste is good for him/her and I saw your idea of teaching by making fun a wonderful opportunity for you to teach them some good science - and you reacted as if I had insulted you! Either you have a king-sized ego or you are suffering from a depressingly low self-esteem.

I hope you take your own advice and chill out - and think it over...for the sake of the children, not for me, as I have no interest in hearing from you again.
