What a strange question: I have never know of anone ever being required to do that, let alone expect others to curtsey to them!
Interestingly, curtseying is the female gesture. You do not ask if males were ever required to bow.
These ancinent gestures are now points of etiquette seen only in royal ceremonies; and bowing (not cutseying), only by the cast at the aned of a theatrical performance.
@wetncthru Yes, but normally only in formal situations such as an award ceremony.
Just as actors traditionally give a curtain-call bow.
Curtseying, bowing and using the title "Sir" and "Ma'am" in a family, as the OP asks about, has NO place at home. That is not genuine respect or etiquette, but submission to pettiness.
