As a full blooded indigenous person who lived through abuse as a kid, had parents who were abused, racism of all forms all my life, had several friends and close family die just about every year of my life, saw violence many times, did violence many times, had violence done to me many times, saw/lived/heard tragedy/disappointment/grief/pain/regret all my life, lived life in the wilderness where everything is hard, cold, heavy, tiring and full of danger ...... mean mug comes naturally now.

I always love it when I can play the dumbest silliest jokes on my non native friends while using my mean mug and watching the looks of confusion on their face as they wonder to themselves .... is he being funny? Or angry? Or psychotic?
