I don’t use the word aura i don’t know what it means and i don’t believe that it is even a thing but i totally get what you mean. I am a muscular guy with very tough features especially when i grow a beard. but, when people interact with me i come off as extremely polite to the point where i am seen soft and non confrontational and i hate it. I used to have a popular twitter account where i was very confident and people would look up to me as a tough guy but in reality i am the opposite and it really sucks
