Since the lockdown, we're only allowed in our offices in an emergency. We have to persuade the university security people that it is indeed an emergency before they'll let us into the building. I don't expect that wanting to take a few books home and add a few more to the shelves counts as an emergency, so they'll have to stay where they are.
I think that last time I was there (March 19th) I finished off the half-drunk bottle of juice I had in there. If I didn't, then by the time this lockdown ends there's going to be a whole new biological threat with which to contend.
