I read a saying once that said unkind words are like feathers blowing in the wind - they are impossible to get back. I lived this one morning at work. I was trying to get through a particularly tricky email and my co-workers insisted on preparing for an event that was 6 hours away. They kept interrupting me, asking me questions about what we had done the previous year. I finally lost it and yelled that I didn't care what they did. After the words left my mouth, I felt sick, especially when I realized that I had worn my cross necklace that day. Definitely not a WWJD moment for me. My co-workers graciously accepted my apology but I still wince when I think about that morning.
Since then, I've tried my best to count to 10 before I'm tempted to say something I'll regret. Sometimes it's taken counting to 10 several times but I feel so much better when I find a way to be kind. It's one of the best things I can do for others. And for myself.
