Let's play a game. You tell me at what point this conversation should have ended:

1- Person A is asking person B for advice about something. B gives the advice and makes nice for a minute and then heads for the door of person A's office.
2- B is stopped at the door by person C who stopped by to ask a question. B answers C while exiting the office.
3- C leaves and B goes back to B's own cubicle.
4- A exits A's office and traps B in B's cubicle, continuing to talk to B about the original item needing advice.
5- B reads email while A talks.
6- B asks A to repeat something because clearly B was attempting to do something else to not become involved in conversation.
7- A finally goes back into A's office.
8- B signs in to blog.
