Darrell: Marina… Marina…MARINA!

Marina: Oh, sorry. I didn't hear you. I was thinking about my homework.

Darrell: What's it about?

Marina: Well, I need to draw a future house for my art class, but I haven't got any ideas. Maybe I should go to the library and look for something useful.

Darrell: Or you can try Pinterest.

Marina: Isn't it a shopping app?

Darrell: Not really. Many people share their works on Pinterest and tell you how they made them. I'm sure you can get some ideas there.

Marina: Sounds like you use it often.

Darrell: Yeah. Just last week I went there and found the A to Z of making chocolate cake—from choosing good chocolate to baking the cake to making sugar flowers on top.

Marina: Really? I'll check it out later. Thanks a lot.
