Recall, “W” was in the office at 7 (or 7:30am), it’s meeting after meeting, some substantive about governing, i.e., bill signing, meeting w/cabinet and/or world leaders, etc., others symbolic (greeting the Superbowl or Little League Champs), and often goes thru dinner time. When there’s a State Dinner, or press conference, it’s easily till 10pm. It’s not all tea and crumpets (at least when done right).
