Midway through the service, the boy loudly said "Mama, I have to pee!"
After taking him to the bathroom, his mother said "It's rude to say 'pee' in public like this. Next time in church, just say you have to 'whisper.'"
The next week, the boy went to church with his father instead.
As the service ended, the boy looked up at his father and said "Daddy, I have to whisper!"
And the father said "Well, OK- just whisper in my ear."
