What's it like to have a sudden urgency on the subway?

I walked from Yau Ma Tei to Mong Kok, resisted the impact of severe abdominal pain, and looked for a toilet in the nearest shopping mall. Dare not run or walk too fast. When we get to the mall, the toilet is on the third floor. After waiting for the elevator for a long time, I finally got into it. Just when I thought I could go to the third floor in one breath, suddenly several people rushed in and forced me to stop on the second floor and then go to the third floor. I promise this is the longest time in my life. I curled up in the corner, my chrysanthemum and willpower were on the verge of collapse, and my whole body trembled (literally). The elevator finally reached the third floor and finally entered the toilet. After I took off my pants for 0. 1 second, it gushed out.
