We have a phrase down here in NZ that goes "I'm a box of fluffys" - same sort of thing as a 'happy camper', although I understand that a 'box of fluffys' has quite a dfferent meaning in the UK (so a little bird told me)..... and 'happy camper' might have a different meaning in different circles also. Let's just say that everything is 'fine, fine, fine'.
Why would it be anything but fine .... tiz 7am and Neil Diamond is playing away in the background. Life just doesn't get any better than this!
