How do you feel??

Such a wierd question. Following a loss, asking those left behind 'how do you feel??' 'How are you doing??' and the likes is such a strange human act. What is the appropriate response?? Fine?? So so?? No feelings?? I don't know?? I'm sad?? I'm angry?? 

How do you think or expect the person to feel in that situation?? Is that a retorical question?? 

It's confusing, upsetting and tiresome. Makes one want to avoid others. 

But like humans, we need something to say in all situations. Such a wierd yet normative act people indulge in.
