when in time of sadness people say to the actual sad people ''i know how you feel, i am very sorry that this happened to you'' to comfort them, they really don't feel it. people might think what kind of trauma a person is going through but they can never feel the same thing unless that happens to them too. so that sentence is totally worthless. also we can not possibly feel sad for someones death who we don't know. there are way too many people dying every day. can't feel for all of them
