She will respectfully mention him as "your son"...
She will respectfully mention him as "your son", as an admission that the mother's share of her son rests larger and ranks higher than the daughter-in- law's share of him as her husband. It is in the interest of the daughter-in-Iaw to avoid mentioning how loving "her son" is to her. That would mean a covert encroachment over the mother's share.
In fact any let-up in the degrees in which the culture is followed at present in an enlightened society on the contrary is considered as a relaxation in the cultural discipline in favour of the daughter-in-Iaw especially when it comes to enjoying a conjugal life. The culture had or has perhaps even now more "teeth", otherwise called "ethics and values"
