Some 20+ years ago, I recall sitting in my elementary classroom and preparing for a standarized test. It is common to gather background information about the students submitting their answers and I distinctly remember the genuine confusion I experienced when I was required to choose just one ethnicity. At that time in my youth, I really didn't understand much racial or "color" distinctions, so I asked my teacher which box to choose. Although I don't remember the exact label back then in the 80's, but it was a selection about my African-American or "black" heritage. So at that time, though still confused in a way, I denied my identity/ancestry of my European father.
I'm sharing this some two and a half decades later to perhaps provoke a bit of reflection on some tendencies you may have that are rooted in childhood experiences. This matter for me was recently awakened when I had an exchange about religious labels or titles. For some reason, I seriously have a difficult time putting myself in a box and slapping a label on 'Who I Am'.
Now, I don't consider myself a psychologist and I'm definately grateful this moment in my past hasn't caused an identity crisis, yet it has led me to explore my own mindset behind labels. Perhaps, there is an important area in your life that sparks mild or extreme emotion....Is it possibly rooted from an impactful occurrence from your childhood?
