听力原文：M: Why？ Jenny？ You look unhappy.
F: I lost my temper at an old man just now, and I feel terrible.
M: Oh, you shouldn't have done that. But why did you lose your temper？

M: Yes, I sometimes act impatiently, honking my horn the moment the light changed, speaking sharply to someone slow to understand. We really should learn various approaches for calming ourselves in stressful situations. I have even found some books to help me. There is some useful advice.
F: Can you tell me something about what you have read in those books？
M: Well, one of the books says that we should allow for marginal error.
F: What does that mean？
M: that means it is better to provide a margin for error Impatient people don't like to waste time, so they cut things too closely, For example, if you are going for an appointment, you should plan for delays.
F: Well...
