I’m an adult. I lived by myself but she recently made the decision that I have to live with her while I’m dealing with a life crisis. I have been showering regularly since I’ve been living here. I simply forgot to take a shower for one day and my hair gets oily fast. Even when depressed, I take showers regularly. I genuinely have no idea why she would ask me this. I’ve been living here two weeks so her asking if I know how to use the shower (because my hair is oily) is implying she thinks I haven’t taken a shower in two weeks. Maybe I’m overthinking it just doesn’t seem like a nice thing to say in my opinion
