That one thing you can't choose,
That one thing you can't pick,
That one thing you can never lose,
That one thing, you can get sick,

It's not your choice,
It's picked for you,
There's no dice,
It's not up to you,

It can't change,
Not now, not ever,
That would be a little strange,
Coz your stuck with them forever,
No matter where you travel,
No matter how far,
Even if you cut the ties or unravel,
You can never change who your parents are.
