I am talking about this situation: >some times people are having a really bad day for reasons you can't see It's not clear how you know someone is having a "really bad day" when you explicitly rule out knowing the reasons why the person is having a really bad day. Maybe they told you they are having a really bad day? That is fine and fairly easy to empathize with. Maybe you are just assuming someone is having a really bad day because of how you perceive their actions?
