I wasn't belittling GrandFather, I was engaging in some self-deprecation. I actually appreciate his contributions, so it never occured to me that someone would take my comments that way (especially him).

Yes, well, I had a good reason somewhere, I know I did, I just mislaid it.

This is known as a sorry-a$$ excuse. I should have marked it with <facetious> or something more creative.

In the midst of all that, somewhere I neglected to say, "Thanks GrandFather, that's a good suggestion." Oh wait, here it is...

But you're right, I should be more practical and simple, and less esoteric. I should use a bubble level instead of a laser sight, because last time I checked, it was pretty easy to use a bubble -- no batteries to run down, no beam to get in your eyes. If it's broken, it's pretty obvious.

So I think you misread between the lines (if that's possible).

Cheers,
