To the child,
Hello you, I hope this message finds you well.
I will admit that the fact that you are reading this is wild and amazing to me. I really don’t know what to write, except that I hope your life has been a good one so far.
If you are curious about me, my profile is open, and you are more than welcome to contact me. I’d love to meet you.
Either way, I wish you all the luck and happiness in the world.

To the parents,
Hello you two, I hope this message finds you well.
I became a donor to help people, and even though my part in it is tiny, it makes me feel great to know that I’ve contributed to the happiness of strangers.
Should the child want to contact me some day, my profile is open, and I’d love to meet them.
I wish you luck and happiness.
