What's the worst thing about you?

One day, I was particularly impressed. After getting up in the morning, my gums bleed when brushing my teeth. I didn't care too much. I ate sand while eating fried rice, and I broke a tooth. I didn't care too much. I was caught in a traffic jam on the road. I didn't care too much. Being late for work, the leader was very concerned, so he dismissed me and immediately told my girlfriend the news. Girlfriend broke up. ?
