I often see videos from the United States on social media: for example, blowing out birthday candles, friends suddenly pressing the birthday person's head into the cake, and some even causing serious injuries because of candles or glass in the cake.

It feels like foreigners joke more boldly than Chinese people, and I find it hard to adapt to that environment.
I even wish that people would always maintain a very polite distance from each other.
Once I had a dream where an elderly person was walking toward me, and in the dream, I only had time to punch him in the face and remind him not to walk so close.
