Of course, it is.  But "digging in" your original position will never
allow us to make any progress here, when there are differences of
opinion.  So please try, however difficult it is.  You will need to
get creative.

My advice is to propose the alternatives which you could accept, and
then take it from there.  There's no need to try to decide up front
whether some compromise will or won't be acceptable by the other side.

I don't know, but Andrea probably will.
