I recently took BSM to the dentist, and I got to teach him two "new" ways to while away the time.
During our wait to see the hygienist, I taught BSM how to play "Dots and Boxes," which he hasn't learned from his friends yet. Unfortunately, upon looking up the actual game description, I see that I taught him to play incorrectly. (I remembered the rules being that each player draws one line on every turn. Now I see that every time a player completes a box, that player is supposed to immediately draw an additional line, which makes the game considerably more interesting.)
Also, due partly to faulty Waze directions, I ended up parking close to 1/3 of a mile away from the clinic. On our way back to the car, I taught BSM a new song. "However," I warned, "Before I teach you the song, I need to make it perfectly clear that you are never allowed to sing this song in the house. Ever. Because it is incredibly irritating."
I then proceeded to sing "Ninety-nine Bottles of Beer on the Wall." I got as far as 92 bottles before BSM cut me off, "Ema, stop. Please. You're right, this song is very irritating." I laughed and sang him just one last verse, from an alternate version of the song: "Ninety-nine bottles of beer on the wall, ninety-nine bottles of beeeer: they all fall down, crash to the ground, no more bottles of beer on the wall!"
