How to react to children at concerts?  Look at this video.  An
adorable child finds his way on stage at a grand piano concert and
begins to play "Twinkle, Twinkle Little Star" while his feet dangle
from the piano bench.  Before his stricken parents can move, here
comes the featured pianist who leans over the tot saying, "Don't stop,
keep playing," and turns the one finger tune into a wonderful duet.

If you aren't patient and encourage the young, tell me, what will
happen to your prized pianos, and societies, when you're gone?
Thrown out to make way for a surround sound system, I suppose!

There are no words that can add to this powerful video.  It states
my point perfectly!
