Escape: Merry Escape

Christmas Eve.As I hurried home along the snowy streets,I got a call from my son.
"Dad? Theres something I want to talk to you about..."
"What? Dont tell me this is about your Christmas present."
"No, its not! Im waiting at grandpas bar, so could you come here, please?
See you later!" He hung up. "That little scoundrel..."
I mumbled with a sigh,but I headed to my dads little bar anyway.
"Hey, Yuto, are you here?" When I arrived, my dad wasnt there,
let alone my son, who was supposed to be waiting for me.
"Hed better not have gone home alone..." SLAM! The door suddenly slammed shut.
"What the!?" Next, I could hear the door being locked from the other side.
Youve gotta be kidding me!
"Sorry dad, but I need you to stay here for a while!"
