Never expect an ISFP to:
*give an opinion without being coaxed into doing so
*get into a loud argument
*run around at a frantic pace to get things done NOW
*not try to help someone who is hurting
Never ask an ISTJ to:
*let go of that to-do list
*stop expecting great things of self and others
*forget painful things that have happened
I would give a longer list for my own type if I only knew another INFJ.
