What is a thing that you would like to keep anonymous throughout your life?

Definitely I don’t want anyone to know that I was brought here by aliens because there was a civil war on my planet. To protect me, as I was heir to the planet, I was dropped off at the hospital and exchanged for another baby.
Now that I’m all grown up they came back one day and landed in my back yard, crushing my doghouse and killing the dog.
They offered me unlimited riches and pleasures. The civil war was over and it was time for me to return and take my rightful place on my own planet.
However, I was so pissed about my dog being crushed that I turned them down.
Don’t tell anyone.
