Has this ever happened to you?

Tell me if this has ever happened to you: you realize that your pockets feel light and you think you have lost your keys (yes, like the keys to get into the school!). You think, well, I had them about 2 hours ago when I ran to the school, so they cannot be too far. You check your man purse, your books, your pockets like 59 times, the classroom in which you currently reside, only to realize that they are nowhere to be found! So, you hop on the motorcycle and drive about a half mile (retracing your route to SNU) and there, at the corner of 42nd and MacArthur, are your keys, lanyard and all. Has that ever happened to you? Because, yes, it JUST happened to me!
