What is the woman’s tone of voice when she first sees the man?

W: Jim, thank goodness you’ve arrived. The class presentation started half an hour ago, and I was just beginning to panic.
M: I’m sorry for being late, Alice. This morning has been a real mess. I didn’t think I was going to make it here at all.
W: Why are you late? Our presentation depends on those graphs you are holding.
M: Yes, I know. I’ll tell you about it later. First, let’s see how we are doing for time. Two groups are still ahead of us, aren’t they? The presentations on the rights of the consumer and the analysis of the stock market. That means I’ve got twenty minutes to sort out.
W: You look cold. What happened?
M: I’ve been standing outside in arctic temperatures for over an hour waiting for a bus.
W: Over an hour? But I thought your apartment was only a ten minute bus ride to campus.
M: In normal conditions, but the bus was delayed because of the weather, and when I stopped in a drug store to call home for a ride, the bus went by. As luck would have it there was no one at home, so I had to wait another forty-five minutes for the next bus.
W: That’s Murphy’s Law, isn’t it? What did it say? If anything can go wrong, it will. Well, we’ve still got twenty minutes to get our wits together.
