Dear Mom and Dad,
I'm sure by now you've realized I've left, and I'm never coming back. Sure, you managed to keep me safe all my life in that bunker, but I just can't take it anymore. I'm going to see the world, whether you like it or now.
I'm headed to Diamond City where I can hopefully find a job and place to live. You think I can't make it out in the world on my own? Well, I can. I'm not that naive little girl that sleeps with a teddy bear anymore. I'm an adult, and I can take care of myself.
Please don't try to come after me unless you intend to visit. I'm never coming back. I just wanted to let you know that I'm okay.
I still love you both,
