What is when a girl pays for dinner?

When a girl pays for dinner, it is simply a sign of equality, and a gesture of goodwill. Gone are the days when it was considered solely a man's responsibility to pay for a date. Today, it is common for women to pay for their own meals, especially when they are not on a formal date. This gesture may be seen as a sign of independence, or just a polite way of contributing to the cost of the evening. In either case, there is nothing wrong with a girl picking up the tab, as long as it is done with genuine good manners and a sense of generosity.
