Bystander Behavior

I know in my life I have been a bystander many times even if it was just a little thing. One situation that stands out in my mind about me being a bystander lately is a little thing but still me being a bystander. When I check my email and I have an email from someone in my Understanding Dance class which has like 150 people in it. That says something on the lines of "I have missed classed and wonder if anyone could email me the notes we took in class." I always seem to just ignore and delete the email. I always think that someone who knows the person better will email them the notes and help them out. Now I really do wish I would have stepped in and helped them out. Since I have been sick and missed so many classes I know how they felt when they needed the notes. I know how stressful it is to miss classes and I really hope someone would step in and help me. I think college students do not speak up against wrong doing because it is just easier to think that someone else will do it and fix the situation. I know that is how i felt.
