Here's a good tip... Ow!!

"Oooh, I don't think you wanted to do that..."
If there's a statement of the (literally) bleeding obvious, that must be it.

Without dwelling on the full, gory details, yesterday I made a fundamental mistake while using a Stanley knife to cut a sheet of cardboard; I failed to ensure that the tip of my fore-finger was behind the steel ruler that I was using as a straight-edge for cutting.
It bled very convincingly and even now, twenty-four hours later, it still stings like an utter bastard.

I haven't done something quite so gormless for a long while, but I suppose that it's one of those things that has to happen every so often to remind us that if we don't take care, inanimate objects will bite. Learning how to use tools safely is something that can be achieved without actual injury, as successful chain-saw operatives will confirm, but there's really nothing like pain for ensuring the lesson is properly reinforced.

I sometimes wonder what it must be like for parents. Just how can they bear to watch their children learn that fire, broken glass and all those other everyday hazards cause blood, pain and tears when they are not treated with the respect that they deserve.
I can't remember my Dad ever preventing me from using any of the tools in his workshop, but he must have had nerves of steel to allow me to use the electric drill when I was less than ten years old. I guess he must have shown me how to use it safely, but I was never aware of "being taught"; I just watched him do stuff and then he would go away and leave me to it.
When Reallyfatbloke acquired his table saw a few months ago, I asked him when he was going to teach his kids how to use it, because the fascination of the spinning teeth of a circular saw has a hypnotic attraction to the enquiring mind.
He went a bit quiet

So, to return to my lapse of concentration.
Blight-of-my-life was surprisingly sympathetic,
"Oh, that's really painful isn't it."
Unfortunately, she then went and spoilt it by saying it was my own fault for messing about with model railway stuff. (Yes, that's what I was cutting cardboard for. The model railway layout is back on course... Oh do stop sniggering and making 'anorak' jokes.)

I wonder if she'd have been a bit less callous if I'd done it whilst cutting a mount for one of her photographs...
