Nobody is perfect

Why do some people doesn't mind their own business? People that will always correct and tell you what to do. Feeling so perfect that in fact it's not. I really don't like those kind of people. When you commit a very small mistake, you will be corrected right away. It is like telling you, you are so stupid, why can't you do this and that. I guess some people are not happy if they don't see you suffer from something. I know some people who do that. People that tells you what to do. People that wants their will to be done over yours. It's hard to deal with those kind of people especially if you are living under the same roof. You tried so hard to avoid them so that you dont have conflicts anymore but sometimes they will make a way to see your mistakes and bite you again. I am just sick and tired of those people and the worst thing is you have to deal with them everyday. Have you been to a situation like this? How did you deal with it?
