Get this picture: Luke is playing Thomas trains on his train table. Rachel Ruth is pulling up on it and disturbing the track. I'm in an adjoining room and cannot see but can hear a frustrated growl.
"No Rachel! No No No! STOP IT!"
I dutifully exhort, "Luke, don't talk to your sister like that. Be nice."
"Daddy, Rachel breaking track!"
"Luke, don't talk to her like that. Rachel is not a dog. Don't talk to her that way."
A moment of silence from the other room. Then I hear a kind voice from my son:
"Ruff! ruff! Rachel. You not dog, Rachel! Ruff Ruff!"
I've got to work on my concrete communication, I thought.
