My uncle (who is a priest) had a baby left on his doorstep 30 years ago. About 5 years ago, the young lady and her parents dropped by to say hi. He was amazingly stoked to see that she was ok and had had a great life. Sadly, she never found any info on her birth family.

What would you tell the child as they grow? It would be tricky, cos you have to keep the secret from the world but is it fair to keep the info from the child also?
