That boombox will not last long if you don't take care of it. There won't be any music if we can't get Bob to remember to keep this thing away from the water. Today there's just one little bucket. The little book that the people who made this boombox put with it to be sure someone did not ruin it by putting it in water. I hate rules.
Some rules are necessary.
For example, the one that says electronic things and water do not mix. Since Bob threw the book away, we could stick a sign to the boombox with the rules on it. It's my boombox. Bob, it is your boombox. We don't want to make you mad, we just want to keep you from being sorry because something you did ruined it.
