The museum welcoming hall

You are on your last day as a guard of a museum one last day before retirement.

You are standing in the welcoming hall of the museum it is a quite small room decorated with paintings. Before you is the map of the museum. Tonight is the last night you are wearing this uniform the last time you have your trusty flashlight on your side. And you are just standing in the welcoming hall holding the letter to your successor in your hands.
