My sister had surgery to remove a mole from her neck, but it worked out. See, it was one of two moles spaced closely together, so any time someone asked her, she just told them she was having surgery to close the vampire bite. And it did look like a vampire bite before it was removed. Nobody pressed it after that.
I had to have a malignant wart removed from my forehead (and before that I spent pretty much a straight year with a band-aid over my forehead to cover the wart), and despite having a plastic surgeon do the surgery, there's still a visible scar. Not horribly visible, but for a while it was completely obvious, and every summer it shows up more because the scar doesn't tan with the rest of my face. But whenever I have people ask me about it, I just look up (like I'm trying to see what they're motioning, even though it's on my forehead) and tell them I can't see what they're talking about.
Honestly, I worked with a girl who had fairly major facial scarring on half of her face (think of the scar on the Joker's face from Batman, kind of), but I was never brave enough to ask her about it. It had happened to her when she was only three years old and she was perfectly fine discussing it, but after nearly two years of working together I still wasn't brave enough to ask. I mean, coming up to
a stranger anyone and asking them about a scar? Who DOES that?
