start:
  say Typing(1000)
  if (firstname) say "Hello {{firstname}}! How are you? 😊"
  else say "Hello! How are you? 😊"
  hold

  say "Ok, good to know!"

  // Ask the user to pick a favorite genre
  say Question(
    "What would you like to do today?",
    buttons = [
      Button("Listen to good music", accepts=["music","listen"]) as music,
      Button("Manage my Dropbox account", accepts=["dropbox"]) as dropbox,
      Button("Tell me a joke") as joke,
