If an analogy will help you to visualize the situation, imagine a meeting
at your workplace or school.
At this meeting, people are discussing a certain issue -- for example,
getting new sidewalks installed downtown or getting new schoolbooks for
the elementary school, or what to do about the new product your company is

product, someone walks into the room, interrupts everyone, then reads an
advertisement for a local restaurant. He or she then leaves without
waiting for comment.
