This makes me realize there are so many things I don’t know. It’s a revelation to learn that things I’ve regularly seen have something in common. Each one is so unusual that I’ve wondered about it, only to become aware of the threads when pointed out.
It makes me wonder how many other things have unseen associations. Intuitively I feel this must be the case on many levels; there are more associations in life than we will ever consciously know. For me, one of the little pleasures in life is the revelation that comes with seeing the bigger picture.
