So, my mom just got home from a 3 week trip to Egypt. She's sleeping on my sister's sofa. My nephew keeps running up to her and growling. We could not figure out what was triggering it.
All the sudden we heard my mom snore.... And Ethan growled back!
Dad, Lois, me, we all fell out laughing. Ethan looks up at us like, "What's so funny guys?" So of course, we laugh harder. He joins us in "social laughter", though he obviously had no clue what was so funny.
