You bought a backpack from an online store. Right after you got it, part of the backpack broke. Now you're writing a review of it on the store website and you explain your problem.

As I started to pull on the top strap, the cheap plastic buckle snapped into 3 pieces.

You live in a small city. The city only has a few buses and no trains. You're talking to a friend who's visiting from a larger city, and he asks about how people there get around.

We don't have much of a mass transit system here.

You're a chemistry teacher. You're giving a lecture to your class. You've finished one topic and now you want to start talking about the next topic.

Moving on, let's review the differences between ionic and covalent bonds.

There's a new employee working with you. You're training him and showing him around. You point to one of the other people you work with and explain who he is.

This guy over there with the dreadlocks, Johnny... he's kind of the boss's right hand man.

You're watching a science fiction TV show about space explorers. The characters find a strange object in space that's releasing a lot of radiation. One character says this while looking at a computer screen.

These readings are off the charts!

There's a new TV show that you've started watching. You're trying to get your husband to watch it with you, so you describe the show's main premise.

It's about this seemingly normal suburban couple who are actually undercover spies.

You're at a bar with a friend. There's a man who's been looking at you, and he just blinked one eye. You think he did it for you and you don't know how to respond, so you tell your friend about it.

I think the guy in the fedora just winked at me.

You've just met someone. He comes from an area that you've been to before on vacation. You really loved visiting that area, so you comment on it.

That region holds a special place in my heart.

You've been asked to go on a business trip. You've just told your husband about it. He doesn't do much cooking or cleaning at home. You tease him by suggesting that it will be difficult for him when you're gone.

Looks like you'll have to fend for yourself for a few days.

You had to travel to another city at the last minute. You don't have a hotel reservation, so you go to a hotel and ask this at the reception desk.

Hi. Do you have any vacancies?

You and a friend are about to play basketball against each other. Your friend asks if you're worried that you're going to lose. You want to tease your friend, so you threaten him.

It's you who should be worried, my friend.

You bought a backpack from an online store. You like it. Now you're writing a review of it on the store website.

The material seems durable and there is a good deal of padding along the back and straps for a comfortable fit.

Your ex-boyfriend called you and invited you to have coffee together. Now you're sitting with him. You want to know why he called and invited you out.

What prompted you to contact me?

You've hired someone to create a new design for a website you run. Now you're talking with your business partner, who mentions that the designer hasn't sent any updates in a few days. You offer to deal with it.

I'll shoot her an e-mail and find out where we stand.

You went on vacation. Now you're back at work. There's a lot of work for you to do. A coworker invites you to eat lunch with him, but you can't because you're too busy. You refuse.

Thanks, but I can't. I have a lot to catch up on.
