Addicted to spending, power, or nicotine?

I’ve noticed that addicts find some excuse to leave early or get “agitated” easily toward the end of a long meeting. May the Present President just needed a cigarette?

From CNN, a quote from Congressman Cantor: about the July 13th meeting with President Obama:

“That’s when he got very agitated and said I’ve sat here long enough — that no other president — Ronald Reagan — would sit here like this — and that he’s reached the point that something’s gotta give,” Cantor said, adding that Obama called for Republicans to compromise on either their insistence that a debt-ceiling hike must be matched dollar-for-dollar by spending cuts or on their opposition to any kind of tax increase.
“And he said to me, ‘Eric, don’t call my bluff.’ He said ‘I’m going to the American people with this,'” Cantor quoted Obama as saying.
“I was somewhat taken aback,” Cantor said. When he continued to press the issue, Cantor said, Obama “shoved back from the table, said ‘I’ll see you tomorrow’ and walked out.”
