Have I told you about "yestermorn"? It is the Boy's way of indicating that something happened in the past. The nap that he took earlier in the day? That happened "yestermorn." That time he got car sick on the way home from Gram & Fa's? "Yestermorn." Oh, and the pizza that he had for dinner yesterday? He ate it "yestermorn."
I share this because it is not only adorable, it is a sure sign of genius since Samuel Taylor Coleridge is credited with coining the term in the poem, "Christabel."
