I'm so sorry that this upset you so. I know exactly how you feel..some people are so brave against such adversity and it just breaks your heart to see them having to deal with idiots like this other guy apparently is.
You are a very special person however to feel so strongly for someone else like you do. Being kind to others doesn't take anything away from you and it just might make the other person's day. Or even week. I hate to say this, but being kind to others is not a trait everyone has, I believe that it is learned and not something we are born with. (JMO) You will get more out of life with a heart like yours.
Is there any chance you will get to know Delano? I don't think going out of your way to befriend him is always the right thing as pity is obviously not what he wants. But if you ever get the chance to have a conversation with him, take it! He could probably use a friend like you!

BTW, let's not even mention how almost every single sentence in my post ends in a pronoun?! What the heck is wrong with me?
