There are many happy memories in my mind. But for me, the most unforgetable time is that my father and I went climbing the mountain last summer. I still remember that day I got a worse grades from my final exam. I felt hurt and didn't know how to go on my study. It was my father who asked me to climb the mountain with him. On our way , he told me never give up climbing and also cheered me up with his plain words. I was touched by his love. I got to know, life is like climbing a mountain. Maybe there were ups and downs, but if you never give up, you can always get to the top. I really benefited a lot from mountain climbing.
