Our poodle pup Gus walks around half of the time with his right ear flopped over the top of his head. He has no idea the inside of his ear is showing, and I keep fixing it for him, thinking, "Why doesn't he feel that?" It occurs to me that in our personality makeup we are prone to have something flopped over that others can see but that we completely miss. Others try very gently to correct it for us, but within a few minutes, there it goes again. I'm sure they are thinking, "Why doesn't he/she get it?"
I won't be able to go through life fixing Gus' ear. And until you or I get a clue about our own quirks, others can't fix us, either. But it might be a good idea for us to stop and consider why people keep correcting us - maybe something's showing that we can't see.
