What are you up to?

A: "Hey Joanne. What are you up to?"
B: "I'm just watching some television."
A: "I'm so bored. I don't know what I'm going to do today and it is only ten in the morning."
B: "Me too. Do you think we are boring people?"
A: "I don't think we are boring. It's just that we don't have any hobbies."
B: "That's right. What do you think we should do as a hobby?"
A: "That all depends on what you like to do. For example, I like to doodle on the notepad, so I'm thinking about doing some real drawings."
B: "I like to play the piano for fun."
A: "Yeah. That can be a good hobby."
B: "Hobbies are great. I'm going to make a list of all the things I like to do."
A: "That's a great idea. I'm going to do the same."
