Mark: Hi, John. Where are you going?
John: I am going to plant some trees in our school playground.
Mark: Oh, I see. That’s why you have a shovel and some seedlings.
John: Yes. Would you like to help me?
Mark: Sure. Let me carry that pail of water then, so we can have something to water the plants afterward.
John: I’m so glad I saw you here. You’re a big help.
Mark: No worries, it’s my pleasure to help. Let’s go!
