I'm quite surprised by this thread, where it has been observed by one pp that 'everybody has at least one tattoo'
Not one of my older relatives, mother, father, aunt or uncle, older cousins, friends of the family, nobody has a tattoo.
None of my own peer group, friends, relatives, brothers, sisters, or any people my own age have any tattoos. And none of my (grown up) children or their friends or their husbands or wives or significant others have any tattoos.
I must live in an alternative tattoo free universe.
But to actually answer the question from OP. There are a couple of people I've worked with whom I've admired and got on with really well, and then noticed, when the summer comes and sleeves get shorter, that they have some fading self-harm scars. One of these was the manager of the shop I work in.(He is mid thirties)
The only difference it made was that I admired him even more.
He is a lovely person, considerate towards his employees, and very good at his job. And he's obviously come from a pretty bad place to a really good place.
A tattoo up his arm wouldn't have told me that. A tattoo up his arm would have told me that he wanted to decorate his body.
I'm as old and judgemental as you like, but I'm far less judgemental about self-harm scars than I am about tattoos.
What I'm trying to say, and probably not doing it very well, is that
self-harm scars don't come as a shock to us oldies nowadays.
It's just another part of your history. Not one person of my age that I know would judge you for it. I've seen loads of people with them.
I don't know what my generation did when they became anxious or frustrated. Certainly nobody 'cut themselves' I don't know where 'cutting' came from. It just popped up in the 90s.
Or maybe it was a 'thing' in certain circles and it just got more popular in the 90s.
My own daughter has claimed to have 'cut herself' when I have forbidden her to go to a late party. Cos 'cutting yourself' is a 'big deal' And then hopefully, I will let her do as she likes.
Turns out that she dragged a pin across her arm, and had a bit of trouble drawing some blood. Didn't fool me at all. Really no blood.
Pinprick.
There's self harm, and then there's just jumping on the bandwagon.
Having scars on your arms would not make anybody think less of you. Don't have a tattoo just to hide self harm scars. Self harm scars are YOU. They show your strength. They show that you have known some bad times and that you have come through them.
I would admire you for them.
