First of all, your fear shows that you haven't completely felt comfortable stealing from others. Secondly, your behavior is actually an immoral behavior. I suggest you stop quickly. Isn't there a saying that you steal needles when you are young and gold when you grow up? Once this habit is formed, it is difficult to get rid of it. At that time, you will steal not only small things, but even gold and silver jewelry, so my suggestion is that you'd better stop this behavior before it is discovered. If you are a child and can't afford these little things, I suggest communicating with your parents. If you are an adult, there is no need to steal these things.
