Machine

A magic machine suddenly appeared in Henry's room and shocked him.
"A Magic Machine..." He read the words on a tag on the machine.
What is that? he thought. That's so weird.
"This machine can take your spirit to anywhere, anytime you want, but the price you have to pay is to change one thing there."
Henry saw a sticky note on the machine.
Anywhere, anytime I want. Does that mean I can go back and do the things that I cannot do before? That's so great!
He looked carefully at the machine.
I'm going to try it, he thought.
