Lily: This is the third time this week that Pat asked me to take care of Timmy while she goes shopping. I wonder if I should tell her how I feel.

Bob: Au, why make waves, honey? You don’t want to rock the boat, do you? I know you enjoy Timmy’ being here.

Lily: Of course, I do. I love having him here. It’s just that I don’t think Pat should take advantage of us. Why shouldn’t I vent my feeling?

Bob: You’d better go with the flow. We are lucky that we get along well with Pat and her husband. We certainly don’t want to do anything would change that. Besides, I think it’s nice that Pat feels free to call when she needs us. We should let well enough alone.

Lily: I guess you are right, Bob. I’ll hold my tongue.
