Yes, rangeroger, that little image helps a lot! Even though I had to imagine very hard. ;-)

I had a lovely little 'hotter than hell' experience last night. I got a bunch of grapes from the refrigerator and rinsed them off with water from the 'cold' tap . . . and a lovely little bit a steam rose up out of the sink into my face -- It only lasted for a second, but I had to laugh when I immediately began checking the individual grapes to see if any had burst!
