The way Kay sprung such a personal and private “children are outside we're going” on Michael in front of 'hired help' whether they be Neri or Rocco, was in extreme poor taste

Michael at least had the decency and sensitivity to send Neri and Rocco out of the Desert Inn room before discussing Fredo with Tom

Now that you mention it, it is strange that Michael was doing paper work with Rocco as such dealings would normally be with only Tom

Rocco just popped up! at Hotel Washington “I'll be in my room Mike”
