When using a method from a enum, why cant you write DayofWeek.daysTillWeekend(DayofWeek.Monday)

in the code, amit shows that you can write:

var today = DayofWeek.Monday

then

today.daysTillWeekend(today)

what i dont understnat is why can't I write:

DayofWeek.daysTillWeekend(DayofWeek.Monday)

There's no reason you couldn't do that, so far as I know. but the example Amit shows is closer to what would happen in an actual application. Suppose you have a bunch of functions and methods in your application, and one of those returns the current day as your Day enum type. You would want to capture that returned data and then use it in another function, rather than explicitly type out what day it is--because the day is going to change, after all.
