Thank you,vakayu.
Translation-
May the best you have ever seen
Be the worst you will ever see,
May a mouse never leave your girnal
With a teardrop in his eye
May you always keep hale and hearty
Till you are old enough to die
May you always be just as happy
As I wish you always to be
(hale and hearty here means strong and healthy.
A girnal is a storage chest-usually for oatmeal -my granny had one)
