Я писаю на штаны

Because I was drinking a lot of water when I was in the waiting room of the office, I peed on my pants and I was in the waiting room for an appointment with my doctor and I began to drink a lot of water, which caused me to really want to urinate but I couldn't leave where I was so I tried to hold on but it was all in vain because after having held on for a while I ended up urinating on my pants
