Pushing Buttons

Lately I've been getting the feeling people really can't be concerned with anything that doesn't affect them. For example, my friend and I were joking and when I joked about the both of us having kidney problems, he said, "No, I'm the one with the kidney problems." And I said to him that I do too, that I had told him so many times about my kidney problems. I thought he was listening, especially since he responded. I thought he understood because he had surgery to repair kidney problems. I guess not.
But asides from that, just about everyone seems insensitive to one another lately: doing annoying actions repetively, forgetting one another, talking badly about other's friends, and even competing with one another's life stories. All of those are currently affecting me. It's times like now when you really realise how alone you are sometimes.
