The opposites.

Normal behavior for noise cancelling head phone use: Put over ears in order to muffle very loud sounds for either ear protection or ability to focus.
Sam behavior: Put over ears at dinner table. Ask 398 questions in rapid sequence in a loud enough voice to hear it through the head phones. Do not stop to wait for answers or...pretty much anything.

Normal behavior for push scooter: use as a tool for getting from one place to another; balance with one foot and push with other to operate scooter.
Sam behavior: take scooter and slam onto ground to very ineffectively break ice, chalk, or any other substance found on sidewalks; use as a swing when turned upside-down and hung from a pine tree branch; quickly spin it in circles to be used as an effective weapon against the ankles of your enemies, both foreign and domestic; after going 200 yards with scooter, sit on the bottom blade and beg to be pulled by the hand grip while you "rest".

Normal behavior for dining utensils: use a fork, spoon, or knife as a tool to eat with while keeping your hands and face free from becoming soiled.
Sam behavior: use fork to flick food as far as possible from plate while eating with your fingers; find bits of food and smash against any hard surface to see "how it looks squished"; take spoon and place between 2nd and 3rd toes and do a funny dance with it for all to see; hide knife in pocket until mother leaves the table to get something from kitchen; use knife to frantically try and cut open: wires, match boxes, unscrew doorknobs, remove t.v. power button, etc.

Normal behavior for mothers of Sams: cry, yell, grit teeth, time-out, spank, etc.
Optimal behavior for THIS mother of Sam: love, love, love that kid. I sure hope he lives a long time. :)
