I was taught a very important lesson recently, but it took me a while to recognise it. When I did, of course, I felt like an arse.
No one has a lock on the Truth. If anyone did, they'd probably be sacked as soon as they opened their mouth because the Truth is the last thing anyone wants to hear. Fortunately, none of us actually know the Truth, we just have what we think are good approximations. It is a powerful instrument, and it should not be used carelessly, or without regard for the consequences.
All too frequently I open my mouth without regard for the consequences, something that I think happens too much in our cell-phone connected Society of Gossip. Humility in all cases must be the rule rather than the exception, and when we start to think that we know better than anyone else what this life is about we break that rule to the detriment of all. I was careless with what I thought was the Truth, but as it turns out I'm just another shiester posing in the body of a man who thinks he knows what he's doing.
I don't know the Truth. I'm just painfully, suicidally honest, and I am trying to learn that honesty is not a license to say whatever you want. Think before you speak.
