My mum only had one eye. She cooked for students and teachers to    16   the family when I was young.
One day my mum came to　17  hello to me in primary school. I was so embarrassed（尴尬的） that I threw her a hateful  18 and ran out.
The next day at school, one of my classmates said, “Your mum only has one eye!” and   19     at me.
I hated my mum and decided to leave her, so I studied very hard. Later I got a chance to go abroad to study and I left my mother.　20　graduation I worked, bought a house and got    21 there. Then I had kids of my own. I was happy with my wife and my kids. But one day someone knocked at my door. It was my  22  !When she stood by the door, my children laughed at her, and I   23  at her, “How dare you come to my house and scare my children!
