I don't know how but I remember my kiddy class English stories as though it happened yesterday. This one must be as old as class I.
There is this simpleton in the village who takes his sick granny to a doctor.
A week later they go back to doc - no relief to granny.
Third week same story. Then the doc asks are you following all the instructions.
Simpleton says yes, doc. Its written shake well before use.
and I shake my granny well before giving her her medicine - 3 times a day.
