Does anyone else have that one friend whose sleep schedule is like an ever-evolving mystery? One day they’ll appear to be asleep for the entire 16 hours that you’re awake, but the next three they won’t appear to actually sleep at all. Sometimes they appear to be on Australian time, other times their schedule has adjusted to somewhere in the middle of the Pacific ocean. (I call this Cthulhu time.) You go a week without seeing them and you have no idea if they’re just really busy, dead, or if their sleep has simply synced up to the exact hours you’re awake and online. The only indication that they’re still in this mortal coil is vague posts about grocery shopping that pop up on their blogs at 4:12AM.
