If my twin sister was over at my house and she went to go to the bathroom, I would not hesitate to follow her in, lean on the bathroom wall, and ask her if she's seen the TikTok of the cat with a mouse on its head. ADVERTISEMENT I might even then decide to have a shower and she would ask if that cleanser I'm using is any good for "our" skin and I would say "yeah it's okay", and then she would buy it before making her way to my wardrobe and shouting about all the things in there that actually belong to her and then I would say "BUT YOU STILL HAVE MY WHITE DRESS" and then my partner would ask that she please leave our house now because she's disrupting the peace.
