First the hardest word: a ladder with very soft rungs, into whose four eyelets you have to hammer nails, plus tuna to keep your strength up – afterwards the ladder looks attractive again and you tick it off your checklist (unfortunately).

The rest is familiar from the last sentence: the axe and the sceptre of the young monarchy with the radio and the open shirts (accept your offer).
