Well dam, thought I was the only one who was ticked off by the "upside down tattoo" phenomenon. Perhaps more accurately, I refer to it as "on glass, from below" view. Thank you for making me feel less OCD about the issue. Another one you may not have noticed is the unnatural mirror image of animals with distinctive stripes or markings (tigers or lions with perfect symmetrical markings or manes). Although I select not to bring it to the attention of the person tagged, because if you don't got something nice to say... well you know.
As to the second question, does the impression of someone being ignorant give them the appearance of being tougher. I'd say yes, and even go as far as to say, it's not just an appearance thing but an observation more often than not being true. Ignorance often results in not be aware of consequences, and with such an absences of fear, who wouldnt' be?
Well that's my 2 cents.
