I look up to my parents. They help me whenever I need it. When I'm confused, they lead me in the right direction. They teach me in a way that I understand. They are really important to me because they understand how I am. I wouldn't make it through all my hard times if it wasn't for them. They are so kind, helpful, and amazing. My mom is the one who is always willing to help me learn, even if she has to repeat it over and over. My dad pushes me to my limit and encourages me to go on. He always understands if there is a problem and does his best to help me. I'm so grateful to them.

Hope this Helps!
