If and when you arrive late for a meeting, what’s the proper way to enter the room?

Trying to act sober. 

Through the door this time and not the window again.....after doing that all my life ,I'm pretty sure there will be another women clever enough to cotton on to what I've been doing for the last fifteen years....
Im pretty sure though that  one day I will find my office...:( 

OMG, I can't remember the last time I was late for anything, I'm usually early.  I have this thing about being late. 

Sit down and shut up until I'm caught up. Being late for meetings is normal at my workplace, you finish the call you're on first.

Enter quietly, listen and see where the meeting/agenda has gone.  This is common with Non-Austrians/Germans, since I work for a Multi National it is common for my firm.  Drives the locals nuts

With properly dressed casual clothes I guess.
Walking straight, head straight up/face straight to forward, arms down(swinging just in rhythm).

just be quiet and sit down
