Today's earrings are an interwoven pattern of many threads of my life. Blues, the colors that sooth my soul. Geometric balance, squares on squares, so pleasing to my eye. A multiplicative array, 4 x 4, touching on the topic of today's 3rd grade math lesson: perfect squares; 16 a square number, 17 a prime. And closest of all to my heart, they were bought for me by husband as a gift for his parents, aged 84 and 89 to give me this Christmas. My mother-in-law and I share a love of blue. My father-in-law loves geometry and design. Earrings and a matching scarf. Such a gift to treasure.
