Escape from the Bottom of the Sea

I asked my parents when I was little. My brother and I fell into the water at the same time, who do you want to save? My parents cursed me and called me a crow's mouth. He said that if my brother really fell into the water, he would step on me to the shore. When I was eighteen years old and taking the college entrance examination, my brother and I really fell into the sea. But at the age of eighteen, I stayed at the bottom of the sea forever.
