One of my earliest memories At about the same age (4 or so). I was in a busy department store with my parents. The place was packed with people, it must have been Christmas shopping or something. I walked past the top of the escalators and spotted a red button on the side near where people were stepping off. Now they wouldn't put a button there if they didn't want a little boy to press it and they most certainly wouldn't have made it a red button. This little boy pressed it and an escalator full of busy shoppers came to a very abrupt halt. I thought this was pretty cool but the angry looking people on the escalator didn't and my parents weren't to impressed either as they grabbed me and hurried me out of there.
