Petrified sound!!

Here I am, sitting in the living room..
Children in bed..
James out Asda, shopping..

Nice and quiet.. ahhh bless!! I catching up Facebook and emails.

Suddenly..

very loud noise.. what was that??
It sound like glass fall off the table..

Have we got burglar in the house??

I went to investigate..

UPSTAIRS.. stupid cat.... playing with marble!!!

That scared me to death!
