I guess all you can really do at this point is go with the flow and when you want to say no thanks, say it, don't let them make you feel guilty either.

How long are your parents staying?

Hang in there, I know easier said then done, but you can do it.

Don't worry about the house, that stuff will get done. They are coming to see you, not your house.

Lots of Hugs, Nikko
