I was in an accident as a child, which damaged my nose. It was fixed at the time in hospital, but ended up looking dreadful. Three years after the original accident, aged 14, when it was obvious there would be no further "healing" I had plastic surgery on the NHS. That sorted the main problem but I was left with scarring. I thought the scarring was very obvious, but was mostly relieved that I was no longer disfigured. I thought the scarring could be seen by anyone standing within 6 feet of me, whereas before the disfigurement was noticeable at a distance of about 30 feet. (On one occasion I came in second in a sport and the press photographer asked me to swap places with the person on the podium who came third, so that my damaged nose would be further from the camera(!) ) The plastic surgery stopped that sort of distressing thing from happening, so I felt I could live with the scars.
I covered the scarring with make up for nights out, but not otherwise.
In my third year at university I mentioned "the accident" in passing to my boyfriend. "What accident?" he asked. "The one that left me looking like this" I said. He just looked blank. He hadn't noticed the scars which still looked obvious to me.
The next day I asked several of my university friends how obvious they thought the scarring round my nose was. NONE OF THEM KNEW WHAT I WAS TALKING ABOUT! I thought the first couple of people I asked were just being kind, but I kept asking around and people kept being puzzled by my question.
Every time I looked in the mirror I could see the scarring. In fact, I still can. But I know that no-one else can.
Honestly, OP, your perception might be way off - mine was!
