I love how fiery they are!
The difference between me liking their fieriness though and disliking some of Harriet's outbursts is that they seem to only get riled when they have a reason to be annoyed or when they are defending themselves. Harriet is just generally mouthy and argumentative for no apparent reason. Like Amy said in that youtube videoclip when asked if they would bring drama to the house, she said they would never go looking to cause fights or drama but would only respond if the drama was brought to them. It seems they will defend themselves. They will let rip if somebody pisses them off but I don't think they go about the place searching to pick fights with people either and most of the time seem pretty chatty and down to earth.
