Caught in Reality

"Why do you care about me so much!?" I shout at him with warm tears falling down my face.
He stares at me not saying anything. Probably from my sudden out burst.
"I'm a mess up! I do nothing but cause you trouble and get people killed!" I couldn't stop shouting. I had to let it all out.
I take the picture out of my pocket and shove it on his chest.
"This is probably a picture of some other little sister you lost, but I know for sure that sweet little girl isn't some demonic monster like me!"
I stared down at the ground still crying. I was too ashamed to look at him.
I turned around and walked away.

What would you do if you found out you had a sister you never knew you had?
Would you try to figure out more information and try to find her, or would you just ignore the fact and carry on with life?
If you ignore the fact you have a lost sister, would it destroy you inside?
If you already had the perfect life and you knew doing this would destroy it, would you still do it?
Why?
