A friendly note to people who don’t speak english all that well.
When we say 'it’s all yours' as we leave the bathroom which you have been waiting for, the thing that is all yours, is the bathroom. And it’s a figure of speach. It doesn’t literally mean that the bathroom now belongs to you. It just means that it’s now available for use, which is kind of a bit like you owned it for a small bit of time. But you don’t literally own it. A figure of speech. Sort of like a metaphor. A turn of phrase. An expression. Just one of those things that people say, that people have been saying forever.
So saying 'you are mine' as you exit the bathroom right afterwards is a bit strange to say the least.
Sorry if this destroys your world view or something. #
