In the last week, I've unintentionally hurt not one, but TWO good friends. How? By not knowing what to say (they'd each asked if I wanted to join them in doing something, and I was uncertain of my answer), and rather than telling them this, just being silent. For years I've known that my "when you don't know what to do, do nothing" approach is not best. But to have two friends thinking "What did I do?" because of silence on my part -- well, that got my attention.
I've heard that a decision delayed is still a decision, and I think it's true. The lesson here for me? When you don't know what to do, SAY SO!
