My friends would tell me, "You have a wash and wear body." Well this past year, something (age, wear, overuse) triggered a frozen shoulder. The xrays show some arthritis. It's not an excruciating pain, more between a discomfort and a pain. But it hurts almost all the time. Still, unless I mentioned the condition, nobody would know.
Recently I began thinking about people you see everyday. Sure, the ones that limp indicate they are in pain. But mostly, there is no evidence of pain in someone's body. So that took me to emotional pain. Even more than physical pain, unless someone tells you they hurt, or act in unordinary way, you would never know.
The conclusion to all these meandering thoughts is, before you judge someone or react to someone's shortness or rudeness or whatever may push your button, stop for a minute. Ask yourself if maybe they are reacting to a pain that is not visible to you.
I guess the message for today is to be gentle with others. You never know what they are going through. And what I know is that compassion will be returned to you.
