Distored Thining - Should Statements

I really dont understand how "should statements" are distorted thinking. Everyone I know uses these. I got brought up with hearing should statements a million times a day. School was should statements, home was should statements, and everything else even more so. Everything is "should" or "should not." There is little else to life. Every second sentence in germany is about what one should do, what one shouldnt do, what one should try harder to do or what one should accept from others... Distored Thining - Should Statements
