Isn't that the truth - my other half calls it the "mm police". I fuss about things that to most people are apparently invisible.
Which leads me on to the idea that trades should be "certified" as discussed a few posts back. I disagree - all it would do is drive out all the old hands that really don't want to go back to college to obtain that NVQ which apparently makes trades "qualified".
And if anyone's interested, here's my latest project from a totally unqualified, not a piece of paper to my name, handyman....(but so far not professionally - maybe when I retire in 2 years from the day job.....)
