Today, I 've done it again!

This morning, the landline car went from Xianyang, Shaanxi province to Xi'an. After boarding the bus, I gave three yuan. The ticket clerk said that the price had increased and 4 yuan was required. I said that I only had three yuan of change, you can see that you can pull me anywhere for 3 RMB. people say no. I got off the bus. get off the bus and wait for the car to drive away. I discovered that the clerk did not refund me the three yuan. really depressing. I think it's not the first time I 've made this mistake. sometimes, when I go out, I feel careless and unstable. the mind is not clear. to punish myself, I ate less bread in the morning and took the stairs to work without an elevator. I advise you not to make such naive mistakes any more, and you should be calm and calm no matter what happens. the reason for writing is to show lessons.
