My neighbour's wife died a year ago....
He asked me if I believed in the afterlife last week to which I replied "no"...
He continued undaunted to tell me that one of the ways the spirits can stay in touch is to gubb up electrical equipment...
He said that in the year since his wife had died she had gubbed-up three computers, his washing machine, the cooker and a microwave oven...
You don't think Snoopy....?
