"I am home" looks like there is no one, let me check the back yard.. where did they go?.. Oh I am hungry.. The kitchen.. He was all alone he didn't know the truth, the boy finally found something, " a lunch " and there is a letter here, his mom wrote
My son I know you traveled, I am very sick, I left the sweet potato which you like in the kitchen in case you return.
The next part was written after 5 minutes.
"you there.. The owner died today, get out"
