One sometimes has funny conversations at the workplace.
A conversation with my boss' boss on weird grammar turned into a discussion of weird food and then to sources of herbs. I mentioned unobtainable, dangerous rue. She seemed surprised that anyone thought rue was dangerous:
"What? I have rue in a pot in my kitchen. My grandmother used to steep it in vodka and called it a tonic. Rue's fine!"
Well then. I am not inclined to argue with the ghost of anyone's Polish grandmother, least of all the one belonging to the boss's boss.
(And perhaps more to the point, now I have real contact with a person who has actually consumed small quantities of rue throughout her life and come to no harm as a result).
Still, probably shouldn't go rolling around in it on a sunny day.
