When it's evidently the result of self-harm, it's certainly a window showing vulnerability. People can take that a number of ways, but a lot of similarly-feeling girls are likely to feel more comfortable. Not something to count on, of course, but if it's a girl that you're quite close to already, they'll probably be fine with it regardless of their own experiences.
Personally, I like them, but it seldom would register as a relevant feature. If they act real broody and emo, the cut is a red flag, but a red flag telling me what their personality already did. If they're acting inhibited and introvert, maybe then the cuts tell me a little more than behavior alone, in that case telling me they're probably very depressed, or experiencing some recent turmoil.
As a whole, signs of self-harm makes me think of emotional vulnerability. How I feel about that is always contextual to the personality.
I'm not sure this is best for a thread of its own. Maybe as part of a more broad discussion of a similar premise, or perhaps secluded to an existing thread.
It feels a smidge like "How do girls feel about me/my traits?" which isn't really what /girltalk/ is supposed to be. Maybe the /boytalk/ thread is best? >>6588
