My wife pointed out the picture below to me. She was surfing a news website and she said "Look! Four generations of the royal family in one picture". Without even thinking I replied "No. It's only one generation".
She proceeded to point and count saying:- "Look. One, two, three, four... See it's four". I said "No, you've got it wrong. It's one overlapping generation according to Watchtower logic". She looked at me with a strange "don't say that in front of the kids" type look. So I said "the kids need to know what a generation is too".
