She was her mother's only support, and the candy trade, perilous as it was, could not be given up.
Katy did not desire to abandon the business she had built up, for she was proud of her achievement.

She was resolved to be good and true, and to her it did not seem half so perilous as to others.

She had even indulged some thoughts of enlarging her business.

Why could she not have a shop, and sell candy on a counter as well as in the street?
She mentioned this idea to her mother, who was sure the shop could not succeed, for she was aware that her daughter's winning manners were more than half her stock in trade, and that her large sales resulted from carrying the candy to hundreds of people who did not want it enough to go after it.

Therefore Katy gave up the shop at once, but she did not abandon the idea of enlarging her business, though she did not exactly see how it could be done.
