I've done it too. I think we all have the urge to let them know what is on our minds at some point. Maybe it doesn't accomplish anything but it sure feels good and maybe that one sentence gets into the heads and makes a home and won't leave. Maybe he will think about it until it eats at him. Maybe, just maybe.
I agree with what Marle said, I saw all those things you did to renovate that house and decided right then that you could do anything!
