Dad's advice is still valid today
Sir -- When I was a young boy, I was returning from Mass with my dad and got my usual treat of an ice cream in our local shop. A display on the counter said: "Spanish doubloons just a penny each." Being well read, I knew that Spanish doubloons were treasure troves beloved of pirates and were immensely valuable.
I pestered my dad until he parted with another penny, not wanting to create a scene, but the wise old man knew I was being taken for a ride. I held on to my golden coin until I got home and proudly showed it to my mother, whose sideways glance to my dad put things in perspective.
The doubloon turned out to be chewing gum wrapped in shiny paper, and I cried all night when I realised I had been duped.
