Issue with my daughter being naked during potty training

Me

I’m trying to potty train my daughter but I’m temporarily staying at my parents house. It’s like they have a problem with her being naked from the waist down and I’m like...? But she’s two, it’s not like we are having guests over and it’s not like I’m running around in the nice. And it almost grosses me out that they’re offended and I can’t shake the feeling.
