I cut. Yeah, and its not because I'm emotional.
I did it for this girl I like, and she has one too on the same place.
(Yes, thats my left arm. The line under it is a scar of my cat scratching me.)
Thats the only thing I ever carved onto my body, nothing at the wrists or anything. Its not deep, and it fades away so I'd re-carve it again about once every 6-8 months.
