I look like an enemy of the US (a Vietnamese), speak loudly (a habit among cooks and a common failing of Chinese people) and have an exaggerated body language. Thinking back, I probably made the Americans think I was a "nutcase," a dangerous person, or someone who challenged and disdained public authority, causing them to just shut me up.
我長相類似政府仇人（越共），說話大聲（職業習慣，也是多數華人通病），又加上肢體語言激烈，如今回憶，可能被美國人誤以為是「神經病」、「危險份子」、「挑戰或輕視公權力」，導致警察要封殺我。
