Every family has one member who smells things before anybody else does. In most houses, that person is the mother.
She is the one who walks in and says, I smell rain. She is the one who opens the book and leans in. She is the one who says the sheets need to be washed not because they look dirty but because she can tell. This chapter of the library is for her, and nobody else. Six scents only Demeter makes, which is how you know they are for the person who notices.
Pure Soap for the drawer she only opened for guests. Paperback for the nightstand. Earl Grey for the cup that got cold. Between the Sheets for the linen. Suntan Lotion for the towel still warm. Snow for the quiet.
If she is not your mother, she is still a mother, and you know her because she notices things. Get her something only you two would pick.
