There is humor in this cartoon because most of us have experienced a person trying to give a gift which they don’t have or which they don’t have with competence.
Too many unsolicited words often reveal the foolishness of the speaker. It’s better to be slow to speak.
Proverbs 17:28:
“Even a fool, when he keeps silent, is considered wise; when he closes his lips, he is counted prudent.”
My Grandfather’s creed was “if you can’t improve on silence, then don’t speak.”
