"We are, perhaps, uniquely among the earth's creatures, the worrying animal. We worry away our lives, fearing the future, discontent with the present, unable to take in the idea of dying, unable to sit still."
Your intentions, just like everything else about you, are nothing but innocent -- but someone who's feeling edgy might take them in exactly the wrong way. Before you get too excited or exasperated, sit down and take a few deep breaths. Try to see things from their point of view. While you know what you meant, you should be able to see how they could have misinterpreted it. The fix is easy.
