How can you take a sabbatical here during this pandemic?
Not “Can you?” How can you?
You don’t have to travel to the other side of the world, or the country, or to another city. You don’t have to quit your job. You can go to the other side of the room. You can ignore a task you never found necessary. As long as it’s a reprieve from your routine, it counts. A sabbatical requires nothing more than cessation of your routine labor. You likely had to step away from much of that anyway.
You’ve never had fewer reasons to avoid taking a break from where, what, and how you are now.
