It is now clear to us that Island Boy knows what we want.
He will often (although not always) pause and look at us for approval before proceeding towards a prohibited area or object. He sometimes even accommodates us and responds to our requests to "clap your hands!" or "wave bye-bye!".
The one "party trick" that never fails is a request to "stick out your tongue". He even understands and indulges us with such variants as "show me your tongue" and "where's your tongue?".
We're so proud!
