"and don't she?" When is it not only acceptable, but essential, to bend the rules of grammar?

Then just imagine her as she is, and a huge string of gold beads encircling her neck, and don't she present a lively picture; and then she is so bustling, she is always whizzing about, and whenever I come in contact with her I really think I am in a hornet's nest.
