Charlie talked to Dowlan today! He came and sat on the park bench and said "Let's talk." Dowlan started talking toy-to-toy and Charlie said, "No! Daddy talk to Tchawhie!" While the conversation was not reported to be all that impressive in content, the fact that it happened at all has me ecstatic!
Later today, Charlie had a glass of water and was running towards the cat saying, "The cat is on fire!" but Dowlan, to the relief of the cat, intercepted him. His imagination clearly works.
