text: Mary: Hey, have you spoken to John recently?
  Peter: Hey, no, why?
  Mary: Hm... He's not answering my calls or messages.
  Peter: Maybe he's out credits or is abroad.
  Mary: Maybe, but it's weird. I see that he read my messages. I'm worried there maybe something wrong with him or maybe he's upset.
  Peter: Why? Have you said something to him?
  Mary: Haven't seen him in weeks, but you know John...
  Peter: Well, yeah. Have you tried calling Anne? Maybe she knows anything?
  Mary: I did, but no news either, that's why I'm worried. You remember the breakdown he had last year, I'm worried same thing's happening right now.
  Peter: I was in Australia back then, what happened?
  Mary: Oh! He had a nervous breakdown after he broke up with Anne. He didn't want to leave his flat, refused to eat, it was quite nasty.
  Peter: Oh my, I didn't know...
  Peter: I'll try to call him, but maybe it'd be good to go to his place?
  Mary: I was thinking about it as well, but I don't want to bother him. He may be on a trip just like you said, maybe I'm just overreacting.
  Peter: I'll go this place straight after work and let you know if he's home.
  Mary: Thank you so much! Keep me posted please!
target: Mary is worried about John as she can't reach him. She's afraid John may have anoher breakdown. Peter will go to John's place after work and will let Mary know if he's home.
