Missing key

Exploration Stage: Bright Living Room
From: Mary
Description: What are you doing here? I'm going to call my parents! What do you mean... when you came in the house and nobody was there but me? Is Dad back from his business trip yet? Are the locks all locked in the lock?
Completed: This key chain is handmade by my dad. It's a cute little model of our family, with a key for each of us. Dad should have been home by now, so we could have spent Thanksgiving with the whole family, but... his model is unlocked.
