For Fun: Taste the lime juice alone, then taste it again after adding the fish sauce, it's amazing how the fish sauce neutralizes the tartness of the lime. Taste again as you add sugar and salt and see how the flavor is transformed with each addition. This should give you insight into how the sweet, sour, bitter and salt flavors work.
*you may add a few dashes of soy sauce instead of the salt
