It makes me so mad that we (even I) judge by looks so much. Pita, your nephew is lucky that such things can be fixed these days, because there was a time when permanent tattoos and piercings really were permanent. Even now, you still get scars, but you can remove these things, essentially. But I don't think he should have had to to get what he wanted. I'm sure he will make a fine doctor (or nurse, or whatever he's studying to be). Good luck to him!
What do those with a huge number of piercings do when they go through the airport metal detectors? I mean, I heard of one guy with over 200 piercings. Just seems it would be awfully inconvenient to remove all those just to fly, LOL!
