I am staggered by some of the stories on here!
I do what KG does, only in Northamptonshire, and research for someone if they ask, since I have the local knowledge. And it is horrible having to go back and tell someone you couldn't find anything, or nothing very much. But I would never dream of asking on Rootschat, my client could do that themselves.
I used to be a professional librarian. with a degree in that and Maths. The librarian bit taught me how to research, and the Maths bit, logic.
One thing Pure Maths taught me was never, ever, to make an assumption. "Therefore" had to mean just that - that the next statement was a logical certainty! I will point out to clients where there might be an assumption which could be made, and leave it up to them whether they want to make it, if there is really no other way through. Never make it myself!
All very useful in this hobby!
