Bonnet

Bonnet, denotes much gossiping and slanderous insinuations, from which a woman should carefully defend herself. For a man to see a woman tying her bonnet, denotes unforeseen good luck near by. His friends will be faithful and true. A young woman is likely to engage in pleasant and harmless flirtations if her bonnet is new and of any color except black. Black bonnets, denote false friends of the opposite sex.
