This is a fun topic!!
I'm quirky about the way I drink Coke...I absolutely have to have it poured slowly down the side of the glass, which has to come out of the freezer not the cupboard, and have one very large piece of ice in it. I make my ice in the smallest (1/2 cup?) Glad plastic disposable cups.
I only use Yardley Lavendar soap in my bathroom.
I have to sleep with 5 pillows, one against my tummy, one against my back, one under/between my knees and another to support my upper arm when on my side. Oh, and my head, of course. (Reckon I'll never remarry unless we have separate bedrooms! No room in my bed, LOL!)
I can't stand the feeling of 'prickly' upholstery fabrics, only cotton/denim for me! Or I have to cover my seat and chair arms with dish towels.
Don't anybody touch my pillowcase or face towels, nobody!
Geez, there is certainly a bit of neuroticism among us!
