As life is reliably imperfect at all times, I'm sure you're dealing with a Difficult Thing. DT's can range from petty to horrifying, hopelly more the former, but it's always something, even if you're the positive-thinking type (I'm not).
I'm tapping out this post on a smartphone in the dark while struggling, as I have every night for eight months, with insomnia and an often-waking baby. This makes most nights of sleep into a chewed-up couple of hours at best, resulting in a sub-optimal, itchy eyed waking life the rest of the time. I highly discourage others from repeating my experiments with sleep deprivation, should you so be tempted.
My thesis here is that, should you be dealing currently with a Difficult Thing, I'll take the night shift of worrying about it off your hands, since I'm up anyway.
What has this to do with typewriters, you ask? Not one small thing.
