I spend time at my mother's house watching tubi or youtube

Would it be normal that mum doesn't want the normal/usual out of me, despite my definition of "being myself", which is "being my normal self"?

My usual is working, me and mum and my housemate are thick as thieves, instead of me right now as an arsehole.

As for my mother's house I'm watching these videos on my mobile phone like bigfoot or aliens or vegetarian videos, my mother as I talk to her would scream at me and I'm doing confrontation to set my boundaries, my values, for why I'm not changing, because if it was what I would usually do it doesn't need changing, it's regular, it's constant, it doesn't need improvement or adjustment and people have got to learn to accept that.

As I'm watching these videos I'm prepared with a wine and a Pepsi Max and not getting drunk, I drink it all in less than an hour.

Mum prepares dinner for me and all of us are happy.
