Old bones

Do you have old bones or new bones....?

Think about this very carefully before you answer!! This is the latest question Joshua is asking after Grandma was silly enough to tell him that she is shrinking. He is now working flat out in his experiment room (no it is NOT a lab according to Joshua) trying to formulate a cure to stop Grandma shrinking and to kill the old bones and make new ones. Please nobody else share their tales of shrinking or illness with Joshua for a while as Grandma shrinking is playing quite heavily on his mind and comes up in conversation a couple of times a day. I am not sure I could handle it if he were working on any other cures at the moment :o)
