Translation:Why do you not respect your mother?
My brain will now probably always connect polish "mother"s with "Why do you not respect your underpants?"
Yes. But unfortunately, "swój" was introduced a lot too late in the course and it can't be used in this skill yet.
It means "your".
"twój" is masculine Nominative.
This sentence needs a feminine form (it describes "mother") in Genitive (because of "nie szanujesz").
