Sleepless

There's something wrong with the time between Wednesdays and Thursdays.

I wake up insanely early, for weeks now. What is it my sleeping mind is hearing?

Though... I remember years ago when they changed the bus schedule in weekends, effectively scrapping 4 of the earliest stops on Sunday. During the first weeks of the change I kept waking up at 6:20 and 6:50 and 7:20 and 7:50 without a clue.

So my question could just as well be: what am I not hearing around 4 on Thursday morning?
