If the sarcastic comeback, the witty quip and dark humor doesn't flow naturally from a child's lips, his elders may worry about him. However, there's a fine line between making jokes that have your proud parents in stitches and being deemed disrespectful. Sometimes it's about knowing when not to laugh.
