In the evening saw Proof again downtown. Such a great play. The tension between Catherine and her sister in the early scenes works so well. It's amazing how often the phrase "Are you sure?" came up. I was a little disappointed by the lack of a beat after one line that was present in the Broadway showing I saw.
"You're in a good mood."
"Why shouldn't I be?"
"I'm leaving soon."
In the broadway version there was grinning during and a pause after "I know." :)
