That depends entirely on the circumstance. I don’t get annoyed if I don’t enjoy the project (certain repairs come to mind) and even when I’m concentrating, if my mood is OK, I don’t get bothered, I can get back on track pretty easily. But lordy, if my mood is bad, don’t anyone dare to disturb me, even sirens on the nearby freeway, I will lose whatever shred of cool I might have had. I can rarely get my focus back. It’s a mood thing, I hadn’t realized that until I thought it out for this Q. Thanks!
