stephanie's wise words from the colonies have persuaded me that it would be invidious to single you out as in need of special training in weaselly things. therefore you are excused the scheduled test and may continue to answer weasel related questions raised on this forum. However, you must guard against complacency and I strongly suggest that you do some quiet study of the subject.
research has shown that you would also probably benefit from studying cetaceans as statistically people called andyc are highly likely to say that an orca is a dolphin like creature when the correct answer is,of course, porpoise. I am sure that you can see how easy it is to make this mistake.
