Questions: Family & Friends

I'm now slightly taller then my mom and I think I'm definitely stronger then her now. We still have funny play fights and she says I'm way stronger then I used to be which makes me feel good

I was curious tho and I asked her if she thinks she could beat me if we fought and she said she still definitely could. We have ordered mma gloves online to have a rougher fight

I asked her what rules she wants and she said none besides eye poking being banned and I just accepted because why not

Do you think she could actually beat me and how?

She is slightly shorter then me and slim build and I'm just an average build for a guy

I’m certainly not. No interest in it. What’s your reasons?

I recently moved into an apartment with my older sister because we go to the same university and we get on well so decided to share the rent.

However, it's been a while since we lived at home together and once aspect of her behaviour has definitely changed.

She's extremly open with nudity.
Not in a creepy sexual way.
But for example, she will come home from gym and throw all her clothes into the washing machine in the laundry and then walk through the apartment naked to the bathroom for a shower. Or she will try and come into the bathroom while im showering so that she can do her makeup or brush teeth etc and the fact that im naked doesn't even seem to register in her mind as a problem.
Is this a normal attitude within adult families?

What are your thoughts on it?

Or is it better to let them stay as long as it takes until they are making enough to make it on their own?
