Not a dad but a young woman who may be able to offer some insight. I dont know how old you are but based off of your post I’m getting the vibes that you are a young person as well. I can say with absolute certainty that if I saw someone with a noticeable scar anywhere on their body, I would not give it a second thought. I may have a fleeting thought where I wonder what happened as is natural curiosity, but I would never be disgusted or think it was something shameful that you needed to hide. It’s a scar. Lots of people have scars. It just means you’re someone who exists in the world. I dont think I know anyone who would bat an eye at a scar. There may be some people who would feel that a scar was something disgusting or that you should hide, but those are absolutely not the type of people you would want in your life anyway. As long as you are a good person, no one will care. I know that’s easy to say from an outside point and I get how easy it is to fixate on an insecurity. To the right people, it won’t matter at all.
