Ah, Gavia my friend, most of us have things rat-holed for "Just in Case" and will occasionally let the fact slip out. The rest of us, who would never do such a thing, are telling a big, fat, fib. And ought to be ashamed.
My long suffering wife, estimates that I'll need to live another 473 years to make a noticeable dent in the volume of things I've got and will defend against all comers (especially wives who want to "clean out all that junk!"
When pressed too closely for the reasoning behind a particular acquisition , my ears get red, I look at my toes and mumble something about "Well you never know..."
If Red reports back that he's able to shoot the eye out of a mosquito at fifty yards, well dang! I've got to get me one too!
Because, after all, it sure would be nice to have handy.........just in case!
Best Wishes, Rob
