So don't you think that a lot of tattoos are deliberately intended to shock?
This summer I saw a guy in shorts who was completely tattooed all over, and had a row of rings in each lip that made his mouth look like the radiator grill of a 1950s American car. As I approached, I was trying to decide whether I'm supposed to stare or not when I noticed I was about to trip on a kerb and looked down. At that point I got a "hello!" in a tone of voice that said "don't you ignore me!".
I think as suggested above peoples motivations will vary.
One of my sons has lots of tattoos, he's not trying to shock anyone, no.
They're just part of his 'cultural' life, I guess we could say.
The other has far fewer, which are significant to him, in ways he would probably bother to explain if anyone asked.
Your interpretation of the guys 'hello' was your interpretation, perhaps biased by your own uncertainty?
Every generation will find new ways of doing things, that us 'grown ups' might struggle to understand.
Just as our parents doubtless did with some of the things we did.
It's best to stay unfazed, if you look around the world, you'll see myriad methods and styles of personal adornment, it's basically self, or creative expression, one way or another.
We swap ideas and methods with other cultures, especially when we are younger, and perhaps more open minded.
It's part of being human I think.
Just cos we personally wouldn't choose to do these things, doesn't mean we can make judgements about the characters of those who do.
There's plenty of dodgy tribes with nary a tattoo between them.
I'm tempted to say, just glance over at the Tory cabinet.. But that would be bringing up another 'thing that's bothered me for a long time'
