I have a big ole sympathetic heart. And one of the things that kills me the most is when I see someone I love dearly hurting and not being able to help. I hate looking at someone important to me, seeing their stress and pain, and having no way of helping. 
Or sometimes I can't help because it's not my place any more. That one is hurting most of all today. You know what I mean? When you have a loved one in your life that you can't help because they won't let you but you would do anything for them?
Yeah.
Well.
Ambiguous as that is, it's how I feel.
