Wondering what to do as it's Saturday, Sandra gets roped into looking after her Grandad. She coaxes Beryl to join her but Grandad soon proves more trouble than expected.
The girls end up baby-sitting Sandra's grandfather whilst her parents spend a day in Hunt's Cross visiting an aunt. However Beryl soon gets fed up with his demands and leaves Sandra on her own with him, only to discover eventually that her mother has turned up at their flat with Grandpa Hennessey as well to look after.—don @ minifie-1
