A truly OCD person would call it CDO with the letters in order, the way they should be.
It is in the right order. It's Obsessive-Compulsive Disorder. I'm neurotic. I know these things! :B
I realize you are on vacation, but if your neighbor at home leaf-blowed like that would it be an issue there? Me, I hate leaf-blowers, including the one my hubby uses. And chainsaws, lawn-mowers and other small-engine machines. I am highly noise-sensitive which stems back from when I was hypoglycemic. I'm diabetic now and do you think it would balance off??? Oh, NOOOOOO, it's worse! Oh, did I tell you I sometimes ramble??? :B So if the noise bothers me I just grab my MP3 so all I can hear is music.
