Actually this is only an excuse to quote a portion of an Erma Bombeck poem, not quite accurately, but from childhood memory. She mocks the idea that you're not to punish a child in anger....as if there's any other time one would.
Never scold a child in anger;
Never punish when irate.
Save it for some happy time --
When both are feeling great!
Save it for some peaceful bedtime.
Try to catch him at his prayers.
As he murmurs, "God bwess Da-da."
THEN you kick him down the stairs!
And so with murder and mayhem. Wait til you calm that hatred down, kids, before you kill!
