The only thing I really remember is not to cut things with a knife in the direction of any part of my own body. The promise was a condition of being given a pocket knife, when I was maybe five years old or something, and I think it probably expired at some point.
I took the promise seriously, understanding the condition and the reason for it well, because she took the effort to explain the reason for it well. I also tend to like not to hurt myself, so I wasn’t really temped to break the rule. It seemed like a welcome good idea.
I have, very occasionally, done so anyway, either being very careful, or accidentally, and cut myself a bit, like when cooking, but not very often or very badly, except I think one time not using a knife but a powered plant clipper, which I don’t think counts.
Well, and I did manage to stab myself in the arm with a sword once, but I was trying to sweep away from myself, and under-estimated the flexing motion of the sword point.
But I do always think about it when holding a knife. And when I cook in sight of her, she does seem to be keeping an eye out to see how safe I’m being if I’ve got a knife or something.
