If you make a wrong decision, something bad could happen or something wrong. For example, if someone says, "Put your hands up" and they are pointing a gun at you and someone else, you either put your hands up or you or the other person may get shot. I believe it is important to think about your decisions before and afterward just to know if you choose the correct one. For example, if you were given to choose between a Resees candy or a Snicker bar, which one would you choose? You may choose the Resees candy but once you eat it, it may taste horrible and you may not like it.
Once you get chickenpox, then only after a long period you will get it again. this is because your immune system knows how to respond to the pathogen the second time. so even though you get it, it won't as severe as the first time.
