Quote from : Is Everyone Hanging Out Without Me? Book

(On differences between men and boys) Men know what they want. Men make concrete plans. Men own alarm clocks. Men sleep on a mattress that isn't on the floor. Men tip generously. Men buy new shampoo instead of adding water to a nearly empty bottle of shampoo. Men go to the dentist. Men make reservations. Men go in for a kiss without giving you some long preamble about how they're thinking of kissing you. Men wear clothes that have never been worn by anyone else before.
