The magic of a nice cozy fire!
You know the feeling, you have been out for a long walk in the snowy and so cold but beautiful sunny day. You are freezing in to the bone and need to get warm.
You come home and that wonderful warm fire and you can instantly feel how the warmth is spreading throughout your body, your muscles start to relax and that popping sound from the fire is soothing and calming for your mind.
I had that feeling today. 
It's the sound that always gets me. It always feels so inviting. The cracking and popping along with the light of the flames is mesmorizing.
