Mom is missing and Dad can’t be contacted. I’m alone. When I went to see Dad robot he hugged me. But that’s funny. How did he know that it was me? Did he hear me? Could he tell by the sound of my footsteps? I didn’t think he could do that. Something might be wrong with Dad’s development. At first I was happy and didn’t mind, but at this specification, there is something wrong with his speed. I wonder why. Is there a reason I don’t know about?
