Tania	Why is your dog whining and looking at you so expectantly ?
Barry	It's the time of day. He always does that around now.
Tania	What does he want ?
Barry	He wants me to take him out for a walk.
Tania	Are you going to ?
Barry	Oh yes, but I like to tease him a bit by pretending not to notice.
Tania	Do you take him out every day ?
Barry	Of course, you have to walk a dog every day because it needs the exercise to stay healthy.
