Sleep whenever

Go to bed early to get up early.

Why do I need to get up early?

It's what you do when you are a responsible adult.

What does getting up early have anything to do
with responsibility?

It probably means you weren't being a drunken
irresponsible idiot the night before.

What if I wasn't drinking?
What if I just like sleeping in late?

You'll have more time to work, to see people,
to go out at night.

How am I going to go out at night if 
I have to be up early?

Just go to sleep.

Right.
