@birdman518 Hi Mitch. I was going to respond anyway before I saw this was you. It is nice to see a picture of you since we have talked so much. That's what I see, you, not an imperfection.
My answer is you don't need to say anything at all. If someone is uncomfortable with your appearance, that is their issue in being judgemental. It is also quite common to have all kinds of skin blemishes and discolorations as a person ages so this is really normal. My 92 year old mom has lots of spots from having spent too much time in the sun and she has had several squamous cell cancers removed.
My husband has a very similar "hole" from excision of melanoma on his hand and a skin graft that is lighter in color because it came from the groin area. It is dished in, and has a bit of redness left at the edge that is slightly raised. As it was healing and red, it looked like a piece of pepperoni. I have to be careful because it is painful for him if it is touched, so I have to check before I hold his hand. There is nerve damage from the surgery because all the skin tissue was removed down to the muscle and bone. It is his right hand, so he has to pause when someone wants to shake hands because that can hurt and cause some electric shocks. He is 2 years past the surgery and has had lots of moles removed by dermatology since them.
I guess I should also tell you that I was the kid who had silver caps on her front teeth. It was painful to always be asked why and what was wrong with me. It affected my life during all my adolescent years. So my view of all of this for anyone who wonders.... is just be accepting of differences and look at the person, not the imperfections. Everyone has imperfections and that's OK.
Thanks, Jennifer... It really does not bother me at all. I just wondered what others did, if anything.
As you said, there are many other age-related "imperfections" to worry about. 🙂
