I have had this controversy about what personality type I am for years with my sister. I knew I am an RR!! She always tries to bring up my anomalies (mistakes) and tries to convert my type to another type like an extrovert or I let my feelings get the best of me. But those are rare occasions and far and few between. Only when I was pushed to no return!
I enjoyed taking the test and it was very helpful to regain my sense of 'I know myself'. I was beginning to wonder.
