The document discusses the use of "too" and "enough" when bargaining for a lower price. It explains that "too" implies difficulty or excess, like being "too tall" or "too fat" to do something. In contrast, "enough" implies sufficiency, like having "enough food" or doing "enough work". The document provides examples of how to use "too" and "enough" correctly and concludes that "too" means more than sufficient while "enough" means sufficient.
