A little boy rolls a basketball around on the tiles. He runs up to me wide-eyed, "What's in the bag?" Quick! Think! ...I'll distract him with a song! "I am sing-ing a sonnnnngggg", I improvise, arms outstretched like leaves. Lyrics are obviously lacking, but the fact that there is a trace of a tune bores him immediately. Back to the rolling. Heh. That's right. Works every time.
