As my friend Linda (who I am yet to meet but hope to do so one of these days) told me some time ago “once the geese find their sea legs you will have trouble getting them off the pond”.  How right she is.  My shouts of “bedtime” are met with an about turn in the water as they all swim to the other bank until, as the light begins to fade, they decide to head up the bank to the goose house.  Night night naughty geese.
