Most abusers have very low self-esteem and are therefore easily insulted or upset. They may claim their feelings are 'hurt' when they are really angry, or take unrelated comments as personal attacks.
They may perceive normal set-backs (having to work additional hours, being asked to help out, receiving a parking fine, etc.) as grave personal injustices.
They may view your preference for something which differs from their own as a criticism of their taste and therefore themselves (e.g. blue wallpaper rather than pink, etc.).
