The plaster cast is in a funny mood.

You said you went to school with a broken bone and a plaster cast, and several classmates laughed at you. Personally, I think you should change your mood to understand this situation. In this case, you can keep a good mood. Being cold can't make your problems bigger. There is no need to be too entangled. Just rest assured and recover.

You can also be regarded as another kind and friendly expression of your classmates. Nowadays, many students like to express their understanding and attitude towards things in some unusual or alternative ways.

As I told you, "I almost fell down the stairs while sweeping the floor today." I thought you would comfort me and say, "Be careful, dear." However, you said, "Just scan slowly." I am very dissatisfied and think that you don't care about me. Later, I found that our stairs were particularly clean. So clean that I don't have to sweep. He is expressing his concern for himself in another way.
