Lucy is at the Natural History Museum. Even before you go in it is a pretty impressive place. The main hall is a bit more spectacular than our front room. Lucy starts studying the science Cripes - this looks like a pretty big spider! By Jiminy - THAT is a big spider. I'm not sure that you would want that walking out of your bath.
Lucy is a fearless little character so it didn't seem like much of a big deal to her to hold a tarantula. Mummy, on the other hand, has had a long standing antipathy to our arachnid cousins. But having watched little daughter handle her deadly foe, she decided that this was her opportunity to confront her phobia. Mummy was very brave. Although looking at this expression I'm not sure that you could say that Mummy and spiders had settled all their differences.
