What will the two speakers do this weekend?

W: What a great day! Hey, Tom, do you want to go to the beach this weekend?
M: Yeah, that is a great idea. Maybe Sara would like to come along with us.
W: I doubt it.
M: Why? You are kidding!  You know, she loves watching the sea.
W: But yesterday afternoon she told me that she would go home this Saturday.
M: What happened?
W: She said that her mother was ill and stayed in the hospital, and therefore she wanted to go home to see her.
M: I am sorry to hear that. Well, What do you think? Should we take some food?
W: That sounds great. Maybe we could have a picnic on the beach. Then let’s take some sandwiches, chips, and uh…some salad as well.
M: We should also take some drinks like Coke and beer.
W: Good. In addition, we had better pack beach towels and sun cream.
M: OK. Please don’t forget to give me a call and let’s go down together.
