Dear Adam,
You are old enough to read this so you got this letter on your fifteenth birthday. You see you know that both your mother and I are not normal people, that we are superheroes, but we do everything to keep you safe.
You see both of us, your mom and I, we were terrified when we found she was pregnant. Both of us were assassins, trained to kill. How would we raise a child? Both of us had shitty childhoods.
But we slowly got used to it. We loved you.
You see Uncle Phil's memories helped us. He was a father to us both.
You were named after him. He was a good man as I am sure people have told you.
The point of this is that now you are at an age you can understand us better.
Both your mother and I are proud of you.
Live your life son.
Dad.
