We had a sister of happy memory who was a true character--capital C. One of her more interesting habits was to seclude herself in our "phone booth." Yes, we had phones in our rooms at that time, but she had this need to get herself into the little phone booth nook and talk away for hours.
We use to wonder if maybe she thought it was private and couldn't be heard from the hall outside but, since its doors are louvered, sound escapes easily, as did her entire conversation!
Anyway, she is now in her heavenly home but the phone booth is still standing, albeit with a rather old fashioned portable phone now instead of the original wall hook up.
The booth is still available---if you can find it. It's in plain sight, yet quite hidden---and therefore well qualifies as nook and cranny #6.
PS. We really miss this sister--a unique character for sure; we don't have anyone that's in her league. I don't think it's something you can "learn," you just are one--it's a gift!
