I do not worry unduly if I accidentally bump into somebody. I usually have serious doubts about the simple everyday things I do. Neither of my parents was very strict during my childhood. I tend to get behind in my work because I repeat things over and over again. I use only an average amount of soap.
Some numbers are extremely unlucky.
I do not check letters over and over again before posting them. I do not take a long time to dress in a morning. I am not excessively concerned about cleanliness. One of my major problems is that I pay too much attention to detail. I can use well-kept toilets without any hesitation.
