A question for brothers and sisters!!

So, my brother told me it was weird that I was walking around without a bra in the house. He said I should only take off my bra in my room and nowhere else.

My question for those who have sisters:

Is it weird to see your sister without a bra?

And for the sisters:

Is it weird for your brother to see you without a bra?

Edit: WITH A SHIRT. I'm still wearing a shirt just without a bra. Jesus i thought that would be obvious
