  Last words.

The Red Cow was very respectable, shealways behaved like a perfect lady and she knew What was What. To her a thing was either black or whiteöthere was no question of it being grey or perhaps pink. People were good or they were badöthere was nothing in between. Dandelions were either sweet or souröthere were never any moderately nice ones.
