Yeah, I have that problem. And it does get just too darned hot to wear long sleeves all year around.

Sometimes people ask me. I have the same problem of not knowing what to say. I usually mutter something about being in an accident. If they keep asking I just say 'I don't want to talk about it'. I think it is pretty obvious anyway that they are self inflicted so I don't feel badly 'lying' or 'misleading' peoples for asking a question like that that is none of their damned business.

Sometimes people even say 'I hope you don't think I am rude in asking, but'. I am sort of tempted to say 'actually, yes, I do think you are being rude in asking'. They have faded a bit over time and with getting a tan. I am trying to find out about this stuff that you can get to reduce the appearance of scars. But slit wrist scars are pretty obvious. And some of them are pattened so they certaintly do look intentional.

It is a hard thing.
I haven't figured that one out properly myself yet.
