Others kept it a secret because they were ashamed of what made them happy.
Harry didn’t judge. but he was persistent.
Eventually, everyone told Harry what made them happy.
Then, Harry would leave a letter on their doorstep.
No, it wasn’t what made the person happy.
It contained instructions on how to keep from being exposed.
Blackmail is such a dirty word, but it makes Harry happy.
And very rich.
