The roommate was greedy for money and repeatedly pocketed the electricity bills for the air conditioner, causing everyone in the room to suffer from heatstroke and be hospitalized. I reported it to the counselor, but she said impatiently. "I hate snitches the most. You are all living under the same roof, and you can't see each other when you look up. What can't you tolerate?" "She refuses to pay, why can't you pay for her?" Seeing someone supporting her, my roommate became even more unscrupulous and even asked us to hand over 50,000 yuan in air conditioning usage fees. She said confidently, "I have a share of everything in the dormitory, including the air conditioner. I have a heart disease and can't blow cold air, and I don't enjoy it. Why should I pay more?" The counselor nodded in agreement, "If anyone doesn't pay, don't go back to the dormitory. Go sleep in the corridor!" Unable to bear it, I checked out directly and took the others to live in a suburban villa. I also made 80 explosive PPTs and sent them to the freshmen group. Now, it was their turn to be dumbfounded.
