it turns out they do have to throw that green thing away. they've replaced it with a blue one which is a much nicer colour.

so the poor old green one stands outside. but what's this ? he has found a friend. it's the water butt !

it's like a salt water fish meeting a fresh water fish. it's domestic hot water heater meeting the cold rain water storer.

they are chalk and cheese. but they get on SO well.
