Several years ago I was in a pub, waiting for the ferry, on the way to visit my sick dad. A guy and his friend sat beside me and started chatting with me. I wasn't receptive because I was bone tired and he turned to his friend and said "damn, shot down again." My response was "I have no energy and my dad is dying. Why do you have to take me not wanting to talk to a stranger so personally?" His response was "I'm dying, too." Longer story short he was a young guy with COPD and destroyed his body with substance abuse that eventually he'd left behind him. His friend confirmed this was true. I always wonder what happened to that guy.
