I would like to be a listener

However I don't know how to be a GOOD LISTENER

I would like to be a comforter

However I dont't know how to be a GOOD COMFORTER

Then what can I be

Neither of these two

When someone told me their own thing

I feel confuse

I don't know what can i be

Listener or comforter

What should I respone

I really try my best to learn but I still can not do it well

What should I do when someone tell me about their sadness next time??
