What do you think?
i don't think its either. i think its wrong.
Wives reveal their true nature when the husband gets poor.
not having money brings out the bad midos in people. it doesnt mean she never was a faithful wife or that she didnt love him, it can just mean that she is suffering and instead of having emuna she blames her husband.
Husbands reveal their true nature when the wife gets sick.
same as above. when a husband is not being cared for, he needs to see it as min hashamayim. if he doesnt, he may come to look elsewhere instead of caring for his wife.
Brothers reveal their true nature when the parents die and legacy is discussed.
"where there's a will, theres a fight..." really they love each other, the moneys getting in the way of the true love...
Friends reveal their true nature when you lend them.
same as brothers.
