oh my.
Seriously, from the beginning, I've started every primitive thread, and some non-primitive threads, this way.
A search of my comments clear back to the start, will show this.
It's usually used in the sense of "Oh my, look what I found here. Isn't this
interesting?" although some other times it's used as sarcasm, "Oh my, look how upset the primitives are about this trivial matter, like three-year-olds getting all bent out of shape because the sky's blue instead of orange."
