A family walking around in underwear?

My sister and her husband and daughter walk around in underwear. My niece came to my house and was walking around in underwear and it pissed me off because I don’t do that in my household. I had to send her home because she refused to put on pajamas pants. Why would a 12 year old girl want to do this? I blame her parents for setting this example. It’s gross and weird.
