How far can people hold back their urine?

Once I went home by bus and was caught in a traffic jam until my pants leaked out. In order to avoid losing control and wetting my pants, I secretly used my backpack as a cover and pulled it out ... As a result, the car jumped and a splash came out ... I quickly ran out of the car clutching my crotch ... I held that thing all the way, dripping urine and looking for a toilet. I finally found a girl who was still locked. Just then, a girl came across the street. She saw me clutching my crotch, holding that thing, bending over and sweating, and asked me, "What's wrong with you?" I said, "I'm looking for the toilet, and now I can't hold it." She said, "The nearest McDonald's near here is also a 20-minute walk. "
