Keys are good sometimes, but not all the time. Most times it's bad because you lose them at some eyeball-to-eyeball convention and you are trapped in your house and you exaggerate, making it feel like it's the beginning of the 1800s and you sit down watching boring news about how some dog saved the day. That's most likely what happens. But keys, of course, can get lost, and it's your responsibility to keep this from happening. What would really be cool is if there was a key that could open any door in the world---wait, wait, wait a minute. I'm not gonna go there, because that sounds like something off of those B-book things when people have ran out of good ideas. I swear there was a recent Simpsons episode about that.
