G.T.
Weird. I have no answer. You say you have visited them fairly often, is it normally all ready for you when you get there? Maybe the 4 day advance notice wasnt quiet enough for them? However you would think they would have apologized for the state of the room.... hmm. Maybe they werent feeling well or something. Maybe they thought the end of the world was coming on the 21st so they didnt bother.... I'm sorta stumped. Maybe you should just ask her "I couldnt help but notice that it seemed like you werent prepared for us to show up, are you okay?" Something like that might bring it to light. You can always ignore it and hope that next time things are back to normal. I dont think it means they dont want you to visit again, seems like there is something more to it than that... maybe personal problems on their end or somethin?
