Sister and I in the (empty) campground laundry room, putting together a quick, fun project requiring a long table (they have) via Youtube video. Sister, suddenly: "Oh! Where's my cellphone?" Us: Look around. Me: "I think you left it my car. I'll go look." I walk to car. Open it. Cellphone not there. Maybe is locked inside their cabin? Hear sister calling me. She has the cellphone in her hand and with a silly grin, calls to me: "We were watching the Youtube video ON the cellphone!"
