documents: #Person1#: Billy, you are late again.
  #Person2#: I'm sorry I'm late. I overslept. Is the manager here today?
  #Person1#: Yes he's in his office.
  #Person2#: Oh, god! I hope he didn't notice me.
  #Person1#: Don't take any chances. I think it would be be best if you told him frankly and promised not to be late again. He's already mad at you for last 2 times. If there is any more, he might fire you.
  #Person2#: You said it. It won't happen again. Do you really think he'd fire me?
