I once said that I didn't have any candy but if they wanted I could give them chocolate. They had a little discussion among each other and concluded that their mum didn't rule out chocolate with nuts. I replied it was dark chocolate and a no nonsense chocolate without milk, sugar, nuts, honey, almonds or such. They were sad. Then I found a tiny package with fruit gums from the plane I did travel with and the sunshine appeared back in their tiny faces. I would have had bad feelings otherwise.
