[Girl2B]

Thank you for detailed explaination . Just goes to show - you don't ask - you don't learn .

No problem! :-) But, you CAN learn without asking. I've learned a LOT of stuff over the years without having to ask. I'm just very observant.

Not being rude but to spend hours on end trawling the and reading variation of answers , is it not easy to ask someone who already has done. The trwling !! Why re-invent the wheel ?

In some cases, it may be more satisfying, and stay with you longer, if you find out for yourself rather than have someone else just dump the info you quest onto you. Also, looking things up yourself might allow you to find out more than the person that already seems to have the info you want. For instance, they might know all the ins & outs of how The Beatles recorded the "Revolver" album, but they might NOT know that there was a first pressing that was made by mistake and only a few copies were sold before it was recalled to re-press the correct version.

That's so deep !! Almost philosophical !!

Thank you! I think a lot. (I think.) I'm always thinking of stuff no one else thinks of, trying to find answers, like; if I'm travelling at the speed of light and I turn on my headlights, does anything happen?
If I spill Spic-N-Span on the floor, is it dirty or is it clean?
If I melt dry ice can I swim without getting wet?
If your woman leaves you for another woman, should you hold the door for both of them?
If Fred Flintstone knew the large order of ribs was going to tip over his car, why did he always order them at the end of every show?
