Bags of Flour

I recently heard this theory in a book I read. It stated that people carry around other people's burdens as well as their own.The teacher in the book demonstrated this by having his students carry around bags of flour and never told them when to stop carrying them hoping they'd wonder what the point was and eventually stop carrying the bags. I realized that this was very true. Most of the burdens I carry are someone else's. If one of my friends or family is sad I am sad too. I carry other people's worry and stress and I'm not even sure why I do it. It's just something that I've always done. After a while it takes it's toll on me and I think,  why am I worry about this problem when it's not even mine to worry about? Yet I still don't let it go. Maybe because I don't know how? I"m not sure what the point of this blog is. I guess this just struck me as something that I think all people do at some point without realizing it. I want to know why people do these things. It's fascinating to me.
