in all fairness, I think that anyone that starts the nonsense should be prepared to give as much as they ask. So if you are asking for a handwriting analysis on a prospective young lady (which I still think is uncalled for) then be prepared with an analysis of your son’s handwriting. Keep in mind that most boy’s handwriting is barely legible, nonetheless be prepared to hand it over first if you ask for it from the other side.
Be prepared to give over the same answers on your child and yourselves that you ask about the other side. They have the absolute right to know everything about you and your child as you want to know about them and their child.
