One evening last week Jen and I found some food spilled all over the floor while both kids were playing in the other room. Jen called out to them, "Who spilled this all over the floor?!"
Nolan promptly replied, "Delaney did it. Not I."
We immediately burst out laughing after hearing his unusual choice of grammar in his response. Nolan started laughing too, realizing he had said something funny, and continued repeating, "Not I! Not I! Not I!" over and over again.
