O curas hominum. O quantum est in rebus inane!

I"ve always tried to understand and reason with people who, through stress or bad life situations, exhibited bad manners or behavior. In my doing so, I have allowed people, or at least given them permission to continue. I finally came to a place where I began to question. Why would you say such a thing? Why did you do that? That doesn't seem right to me. Don't you think we should talk about this?
Well, this didn't seem to fit the criteria of a good relationship. If I were to reveal step by step a list of things my brother did, and my response, or my sister, my neighbor, my brother in law, etc...I think you would agree, "What assholes".
I share responsibility in that I allowed too much piss poor behavior for too long. And my response was sudden. I pulled the plug. We have all gone our separate ways.
The night before, my sister in law left a drunken message looking for a call back. Last night, my sister left a message. A month ago my other sister in law left a message for a call back. I'm just too burned out. No one seems to understand that I just want to be left alone. It's too late for the, "But we're family" bullshit. I spread myself thin trying to support them in their folly. I'm done. I have a hard enough time taking care of myself.
