I consider him a two-faceted man. He can be polite and willing to share his knowledge about dolphins with us but he can also be rude, bossy, selfish and arrogant. He does not treat people with respect so I would not like to be one of his crewmember. He swears a lot and he always knows better than the other people.
There is one thing about Geoffrey one can’t deny. He knows a lot about dolphins and he is able to make people experience them.
