  Amy: I can't reach him. I hope nothing happened to him
  Amy: Did you try to call him?
  Bob: Yes, voice messaging’s on.
  Bob: Did you try to text him?
  Amy: Yes, and he didn't respond to my messages
  Bob: I hope he is ok
  Amy: I hope so too. I will call him again, but in the meantime can you pick me up?
  Bob: Sure, what time?
  Amy: I don’t know, how fast can you be?
  Bob: I finish my lunch and I’m on my way? One hour?
  Amy: One hour sounds perfect
  Bob: Ok, I will be there
  Amy: Thank you so much!
  Bob: No problem. Keep me posted if anything changes
  Amy: I will. Thank you again
