A joke was told for a long time, and finally it said how to repair the motorcycle.

My girlfriend is cheating on me recently. She always goes out with others at night and takes a taxi back at night instead of driving to the door. I peeked at her cell phone and she flew into a rage. One night she went out, and I hid on a motorcycle at the corner, waiting to see who would pick her up. It turned out that the motorcycle leaked oil. Sorry, this car has only been bought for one year. Is this oil leak guaranteed?
