What are some things that are considered inappropriate for আপনি অথবা in the family?

For my family: literally nothing lmao. I have no filter because no one in my family has one. Except my grandma lmao.

For me personally: physical contact of any kind that I don't initiate.

For my family: The N word, even if it's ব্যক্ত দ্বারা a black person. That and kids saying "Lie." (Never got the "lie" one to this day.)

For me: Using your higher position as an excuse to be a dick to me অথবা treat me like a child, telling me who to vote for.

In my family, it's disrespectful not to greet your elders properly and দ্বারা their native greetings. Like আপনি can't just say "hi". For me though, I personally don't like it when the younger kids refer to me as ma'am অথবা like any other greeting though.

It is disrespectful to launch my great uncle's lifeless body across the room after he's had his daily stroke
