Perhaps only Mom and Kiddo understands the reference from the photo above. It is from What Happens on Wednesday, reviewed at What Do We Do All Day? in her Urban Book Series. Cate really enjoyed it.
Cate loves her swim lessons. She has her first little teacher crush on "Mr. Trey", the young man teaching her class. Almost everyday she creates a love note of some sort. Here she has created a pool from wooden blocks. The blond Caucasian wooden person standing on the edge is Mr. Trey and the cup of wool balls is his ever present cup of coffee. Cate is the only girl in the class with three very active boys.
