This is a great piece. It's short nut gets right to the point. I did notice in a couple of places you used it's instead of its. A way to remember which one is which is to think of the apostrophe as someone holding your place in line. In this case the i has to go to the bathroom so asks the apostrophe to hold its spot. So what was it is becomes it's. Then that makes the other its the one that shows possession. You painted such a mental picture in so few words, I'm impressed by your intuitiveness. Being a thorn may not always be easy or comfortable but it can make a difference! Keep writing!
