A. Hello, Susan!

B. Hi, Jack! What are you doing with the laptop?

A. There is going to be a barbecue and cooking competition at our school next week. I am helping to organize it.

B. That sounds interesting. What do you have to do?

A. Yes, it'll be very interesting, but we have to do a lot of work to prepare, such as: choose the music and invite the band to take part in the program, buy food, design posters for the competition.

B. Do you need some help? I am not busy this weekend.

A. Oh, great, Susan! Can you help me buy some food from the supermarket?

B. I can do that. Give me the list!

A. OK, I am going to send you the list of food via messenger. 

B. Do you want me to help with anything else?

A. That's it for now. Thank you so much!

For example:

A. Hey, Nam.

B. Hello, Mai! What are you holding in your hand?

A. There are tickets for a mini sports tournament at our school.

B. Oh, When is it? I heard about this event.

A. It is going to be held next month. I am helping to organize it.

B. Mai, can I become a supporter of this event? Can I do anything else to help?

A. Well, now we need help with posters. You're good at design?

B. Yes, I can do it. When is the deadline?

A. That would be great. We need it this weekend. 

B. OK, I will finish it as soon as possible.
