What is something that makes you feel sad?

Something that makes me sad is when people don't try, especially in school. I know they can do better but they have to think that and push themselves. They can do better if they put their mind to it. You can pay attention and understand the instructions or the subject. Being confident in school will get you far. I don't know how else to help them if they don't try or take advice. I don't like to see them being weak minded when they really are strong and can be much more.
