I contacted her toward the end of January to try and arrange something in advance but she mentioned she was due to be moving from her apartment soon (whether that was the one she worked from or her own personal place I have no idea) so she wasn't sure specifically if/when she would be available around that time. I mentioned moving it back to later on in February and she didn't mention anything then about packing it in so it must have been an abrupt decision? If it was her working apartment maybe she couldn't find another suitable place, or just took that opportunity to retire?
