And say what?! That would be a swift way to get "MTF surgery".

I was thinking more along the lines of a twin-size aero-bed. You could set it almost anyway you can find the floorspace. Or one of those foam chairs that fold out to a bed. Still the tricky thing would be keeping it for yourself. They would surely expect you to give it up for the guests.

Im sorry, justafriend, i didnt mean to be harsh. But grannies can be very mean if you are in any way dependent on them. They want you to stay home to care for them in their old age, but they realize theyve made a deal with the devil.
