Passive - Bring something with you to the meeting. Work items to work on while you wait, or a book etc. I am a fan of printing off technical stuff and keeping it on hand when bored. Looking busy is a good tactic to avoid the 'good idea fairy'

Aggressive - start launching into the topic. This can meet resistance 'oh hold on we are waiting for xyzzy to show up', response: I have too much work to do, call me at x1234 when you are ready to start.

Story time: I had a boss who would tried to establish a social bond with his people. He was not a techie, so there was none of that to build on. So he did the typical 'lets talk sports' because that was the only thing he knew. As such we would waste time at the weekly team meting for 15 to 20 mins. Only one guy would really engage with him. He was surprised when we all said how much we hated the wasteful weekly meeting.

What he should have done, to accomplish the social binding and understanding of what we were doing was to met each of us and talk individually. Oh well.
