Yes, of course, but when asking for outside help (especially when your
own reasoning has not brought the solution - which is probably the case,
otherwise why ask for outside help) it is best to tell the facts, all
the facts, and OK, after that maybe your ideas. But concentrating on the
facts is so important that even explaining them to your cat (kid,
spouse, flower, etc) often brings you enlightment.
