This comment makes no sense unless you're trying to say you wasted hours in the morning and couldn't shift your schedule to wake up later in a fancy way.
Naw, many night people are night people because you can always stay up another hour but you can't have woken up an hour earlier in response to things happening during a day. I think that's what gp is getting at.
Those aren't really night people as much as they are slackers, which loops around to the point it isn't about morning/night at all as much as personal attitude towards not wasting your finite amount of time.
