Fifteen years and still learning new words

I have had my African Grey, Einstein, for fifteen years now and he still surprises me. Last week he called my wife by name when she walked through the door. His vocabulary is well over three hundred words and he uses many of them in context. Yes, he demands attention and gets grumpy if ignored, but the bond we share is like nothing I have ever experienced with any animal. Absolutely worth the commitment for the right owner.
