I'm sorry for being 'testy'; it's been a very long week, and I'm about used up. Newbies are newbies, educated or not, and I know that. God knows I've done enough of that myself!

But it takes a bit of self-control -- never one of my strengths -- to avoid snapping at people who ask unnecessary questions, like yours. As in every area of life, solving problems is maybe 20% technical and 80% people, and I know that too.

There's not much for me to take back; everything I told you is both true and relevant, and if there's a way to 'take back' having said it badly, I've never discovered it! Again, as God knows, it's something I could have used many, many times.

So, yes, you 'bothered' me, and yes, your questions were unnecessary to the function of your pool. But it's part of the learning process, and I responded badly. I hope you'll forgive me.
