Where is Jack?

Marcel arrived at his house just to find his grandma's tavern was very quiet. He opened the sliding door roughly and ran up to the second floor, where they lived.

"Grandma!" He exclaimed, but there was no answer. "Grandma!" he called again.

Marcel's hands began to shake. All the bad thoughts popped up in his mind. He searched all over the house, but did not find his grandmother yet. Finally, he was about to run back to the outside, but as soon as he reached the door of the tavern, the door opened from the outside. He immediately let out a sigh of relief.

"What's the matter, Marcel?" The grandmother asked before suddenly receiving a hug from her grandson.

"Where have you been, Grandma? Why did you go out without locking the door?" Marcel asked breathlessly.

"I just went over to the neighbour's house for a while to borrow a can opener. What happened?" Lillian asked confused.
