I also have a hard time answering it.

Well, that's reassuring.

instead of "make me a sandwich while you're in the kitchen" "oh man sandwiches sound delicious, would it be possible for me to get one too while you've got the bread out?"

The point of that example was that it's not a "while you're there" request, it's meant to be unreasonable--one end of a spectrum where the middle is murky. Someone else didn't parse it as I intended either, so I'll try to make it clearer.

I am this very moment in the process of struggling with the question

Go to bed, LW will be here in the morning. ;)
