It's a long drive to Cathy's house. I'd better lock up the house and head for my car!I'll grab¹ my keys and...huh? My keys! They are not in the usual place! Oh no! I've lost my car keys! The extra house keys are here, but mom has my extra car keys! No keys means I can't pick up Cathy! What am I gonna do?
Granddad: Think, Victor! Think! Retrace² your steps. What did you do with those keys?
Victor: Good idea, grandpa! This afternoon I drove home from playing basketball and took a shower.
Granddad: Did you change your clothes?
Victor: Ah! The basement! Maybe the keys are in the pocket of my dirty jeans! I've gotta, hurry! Cathy doesn't like to be kept waiting! Please keys! Be in here somewhere! No luck! They're not here! Wait! Maybe they're up in my room! They have to be in here! They just have to! Where are those keys? Here? Nope! Not here! I give up!
