i once knew the answer to this.....lol...........now i cant remember it clearly to explain it.

ocpd the obsessions and compulsions dont take place. everything you do makes sense to you. it is just part of the ritual of how things work. it isnt really distressing. it is a lifestyle you accepted. it is just how things work. it isnt a bother or inconvenience like these thoughts and rituals are to an ocd. it doesnt disrupt life because it is part of life. part of your personality.
