I agree here, I'd say you should let them figure this out on their own.

Can't you try their reset button?

(Also known as their belly button)

I can't speak for other ISTJ's, but I personally think that is an excellent way for the button pusher to end up in the hospital, or at least put on the "not my friend" list. Belly button pokes/pushes are by invitation only, and so far none of those invitations have been sent out. Ever.
