Happy Birthday! It sounds like you are having a fantastic day.
One time my MIL gave me a nightgown that was so plain. It was just weird, and my husband looked at it and asked me if I asked for it. No, not sure where the idea came from - but oh well, it was her mother that gave us twin sheets for a wedding present. (Which turned out to be handy when we rented a furnished apartment and the 2nd bedroom had twin beds.) And, yes I do wear nightgowns to bed, so I don't believe she was trying to tell me something.
