If they ever try to take up a life of crime my kids will be utter failures. They leave far too much evidence behind: dirty dishes on the table, half-read magazines on the chairs, clothes strewn about their rooms, forgotten toys under the couch, unfinished projects everywhere. A detective's only challenge would be to shovel through the mass of clues in order to pick out the felonious ones from the noisy background of misdemeanor mess.
And of course, leaving a trail of trash is a universal human foible. We tend to expect others to clean up after us, and we too seldom look back at where we've been ... I as much as anyone.
Without littering of this nature, where would archaeology be? The trash of today becomes the clues of tomorrow.... :) -- Bo Leuf
