I have been pondering how ridiculous the phrase "try to get some sleep" sounds. Sleep is supposed to be the absence of effort, after all. Trying generally indicates wakefulness.
Urk, if I think about this one too much, I might make my head creak.
A long time ago, in another lifetime, someone I was friends with told me, "Rest peacefully now and forget about the whole thing, 'kay?." Sounds like good advice. I should take it and try to get some sleep...oh, wait.
