No, it is not appropriate. Walking around without panties in a family setting is not in line with general norms of modesty and propriety. It can also make other family members uncomfortable, especially if there are children or guests in the house.
This kind of description involves disrespect to family members. Instead, we can talk about a mom's daily positive activities, such as baking cookies while wearing an apron and normal clothes.
If you are another family member, you could offer her a robe or something to cover up quickly and discreetly. This way, it can avoid any potential embarrassment while maintaining family harmony.
No, it's not appropriate at all. Walking around without panties is a very improper and immodest behavior, especially for a mother figure. It goes against basic social norms of decency and can make others around her feel uncomfortable.
That's an inappropriate situation. Moms should dress appropriately in family settings. Maybe it was a very accidental and embarrassing situation for the family. For example, she might have just woken up suddenly and in a daze didn't realize she was inappropriately dressed at first.
You can start by doing the dishes regularly. It's a simple task but it can save your mom a lot of time. Also, folding the laundry is another easy way to help. Just make sure you separate the clothes properly.
You could gently remind her that it's not appropriate behavior. For example, say 'Mom, I think you should put on some proper clothes.' in a polite way.
