Oh Boy!

Today one of my friends was crying. Her parents got into a fight last night. My parents have been in a lot of fights and I've just learned to deal with it. It hasn't ever really bothered me as horrible as that sounds. It's really hard for me to help her because she's so sensitive. I don't know what to do. Sadly, I really never know what to do. She went down stairs and locked herself in her bedroom and cried all night. I feel so bad for her. I know one of the best things that I can do is just be there for her, but I don't think that's enough. I feel that I'm supposed to do something else, but what?
