Apologize

This afternoon, I am going to go to my grandmother's house with my father. When I went down the stairs, my father asked me if his jacket didn't look good. I saw that the zipper of my father's coat was too down. I helped my father to pull up the lock. When I finished, I said, "This is good." Dad looked at it. I want to move the zipper, and the zipper can’t move. I used to look at it, yeah! It turned out that Dad’s shirt was caught by the zipper, and the zipper did not move. When Dad got the zipper, Dad saw that his shirt was broken and his father was very sad. Because I pulled his zipper up, so I broke my dad's shirt. Dad asked me to write this diary at night to write this, and I apologize to Dad. Therefore, I seriously wrote this diary and said that I apologize to my father.
