You walked into the rather large house of the child you'd be taking care of for a while. The parents said you'll find the child in the living room. You set your bag on the table and took your jacket off

The house was silent and still. The clock on the wall not making a single tick or tock. You could hear the boy writing on something, most probably paper, from where you stood.

You could explore the house, or go straight to the child.
