I don’t think we should crucify this girl just yet. You don’t always realize that someone needs help. Sometimes you are just thinking about someone else.
I don’t think I am a bad person because I don’t walk around all day focusing on other peoples needs. I try to help people and I try to anticipate their needs, but things do slip by. It would have been mean if you had asked her for help and she refused.
I think you should find that girl and apologize.
