To my friend Paul, I say that most of the time we have votes on Thursdays at 5:30. This is before 5:30. I agree with you that if we were to sit on Thursday evening, it would conflict with what you're talking about. But this is only Thursday afternoon, and since most of us have to be here until 5:30 and beyond for the votes, I think it would be more appropriate to leave at that time.
