Freya: I can't find my camera, Archie.

Archie: There it is. It's under your bag. Why do you have to bring it to class?

Freya: I must take it to my photography class today. By the way, I didn't understand that email you sent

me yesterday.

Archie: I didn't send any emails yesterday.

Freya: Well, you might have sent it earlier. But I got it yesterday.

Archie: I can't have sent you an email. My phone hasn't been working for a week.

Freya: Somebody must have used your account. The email had a link to a competition, but when I clicked on it, nothing happened.

Archie: Oh no! You shouldn't have clicked on the link. You've possibly downloaded some malware onto your phone.

Freya: That's terrible! You should have warned me earlier.

Archie: I didn't know! Anyway, you might not have downloaded anything. It's possible that you were lucky. You just need to wait and see.

Freya: Anyway, you need to warn your other friends. That email could have gone to everybody in your address book!
