Must the wife tell her friends what her husband brings home in the way of food and the like, and is her failure to do so considered an ungrateful act?

A woman is not obliged to mention what her husband brings in terms of food or other things. It is better to refrain from doing so if there is no need to mention it, and this is not a denial of the husband's kindness. Indeed, it may be necessary not to disclose it if it is for the purpose of boasting and showing off.
