My Role Model
When comes to role model,people always think about some pop stars or heros,but my role model is my grandpa.Grandpa is a simple maths teacher.when i was a child,i always thought to be weak because i'm thin and weak in sports and maths.Not only my teachers and classmates,but also my mother always scold that how stupid i was.But grandpa didn't think so.Instead of scolded,he always encouraged me that "don't give up,just try again".Besides,he also helped me with maths.Because of his patient and good teaching,i found maths was so interesting and became good at it day by day.I never forgot the day i had got the first full mark.when i showed it to grandpa,he smiled and shared the happiness with me.During all these years,grandpa has been like a big tree to me.Under the tree,i have felt comfortable,secure and been well protected by him.Because of his encouragement,I overcome lots of difficulties and find back my confidence.What's more,I became to know that very often a disappointment some times can becomes a turning point for a wonderful experience.Now I want to express to grandpa that how grateful I am,and his words "don't give up,just try again" are aways in my heart.
