"We respect your family."
Translation:Szanujemy twoją rodzinę.
You uses "Twoje" if you are talking to one person and "Wasze" to group of people. It's not really hard, right? ;) "One" means "They" but if "They" includes only women, girls, neuter things or feminine things. "Oni" refers only to group of men, boys, masculine things and if such a group includes at least one man, boy or masculine thing. ;)
