You're standing on your neighbor's stoop, waiting for him to answer the door. Your mother made him a casserole last Friday and he still hasn't returned the dish.
Why couldn't mom just do this herself? You think to yourself with an audible sigh.
Suddenly the door swings open and a young boy you've never seen before beams up at you. "Hello!" he says cheerfully. "Are you here to see Grandpa?"
Grandpa? You think. I didn't know Mr. Jethrow had any grandchildren! I thought he was an ancient bachelor... hmmm.
"Yeah," you nod after a moment. "My mom made... your grandpa?... a casserole last week and I just came to pick up the dish."
"Oh! I know where that's at! Come inside a second while I go get it from the kitchen!" The boy opens the door wider and motions you inside. After a few paces, he motions toward an open door off the main hallway. "You can have a seat in here. I'll only be a moment."
He waits for you to enter the sitting room before bouncing back into the hallway. As he leaves, he smiles at you and adds, "I'm just going to close this. Grandpa's sleeping and I'd hate to wake him. Be right back!"
You don't think a thing about it, until you hear a lock click from the other side of the hallway.
