Sorry to hear about your mother, hope she'll have only a mild case and all other members of your family test negative (though somebody might want to isolate with your mother, not nice to be all alone for a week or more at that age). Anyway, take all the time you need. If you'd rather spend your time with something else right now, I'd be willing to take over. Or maybe you'd like this as a bit of distraction? In which case I'm still available to answer those questions you foresaw having. Whatever you need, just name it.
