In the car, making the last leg of a two-day road trip, the boys want something to drink. They have been complaining that the water in their water bottles is warm and “yucky”, so I offer some of my iced tea. B still has water in his water bottle, so I pour extra tea in R’s bottle so they can share.
B — I don’t want to drink from your bottle!!
R takes a napkin and wipes the spout of his bottle and hands it to B.
R — I told you I wouldn’t let you down!
