It was just the four of them after the war. Fortunately the goat was female and could contribute by supplying milk, and fortunately the humans were vegetarians and so saw no need to slaughter her (but she was always careful not to turn her back on them – you never knew).
The humans amused themselves by stripping down and rebuilding the old Toyota and teaching the goat English. Her accent and vocabulary weren’t too bad but the only examples of writing were on the gravestones – all those foolish book-burnings – so they didn’t bother with reading skills.
Could have been worse.
