My lesson from our piano
When my two daughters were toddlers, they would find the loose change that fell out of my pant pockets and for safe keeping, would insert the pennies, dimes and nickels between the keys of our piano. Needless to say that after a while, when a key was depressed it stayed that way and soon the piano could not be played. We were a young struggling couple with two children and the thought of spending money we did not have to retrieve pennies from the keyboard seemed frivolous. But, my wife loved to play piano and it was now challenging to play.
