dialogue: Daniel: Have you used Uber recently?
  Simone: No, I try not to use it
  Caesar: why? it's such a great app
  Simone: I don't like how they treat people, drivers etc. I think it's a wrong way of progress
  Caesar: oh, you're exaggerating like all lefties
  Simone: and you just don't have empathy, like all "righties"
  Daniel: LOL. I only wanted to ask if your app work, because I can't open mine
  Daniel: I didn't intend to start a third world war between the left and right
  Simone: haha, ask the capitalist, I haven't used it for a while, but yes - I can open it
  Caesar: works perfectly, I use it everyday 
  Caesar: try to uninstall and instal it again
  Caesar: Maybe there is a bug, so it's worth to check for updates
  Daniel: it's helped! thanks
summary: Daniel can't open the Uber app. Installing it again solved the problem.
