I'm so heartless. I watched a kid get hurt and I just did nothing.
Did something stop you from helping? What did you want to do that you didn't?
I just couldn't bring myself to do it.
I know it can be scary to step out of your comfort zone and help someone who needs it. But imagine you were that kid; wouldn't you really wish that a person watching would step in. Sometimes you have to take risks like that, but it is usually worth it in the end.
It's sad, it could have turned out bad and I wouldn't have been able to live with myself if that was my child. I know I can be brave some day.
I can see that you feel bad about it, and you had no ill intent by not helping. If you're ever in that position again then try really hard to push yourself into helping.
