'It's all right,' the Rat would say. 'Badger'll turn up some day or other - he's always turning up - and then I'll introduce you...but you must not only take him AS you find him, but WHEN you find him.'
'Couldn't you ask him here - dinner or something?' said the Mole.
'He wouldn't come,' replied the Rat simply. 'Badger hates Society, and invitations, and dinner, and all that sort of thing.'
'Well, then, supposing we go and call on HIM?' suggested the Mole.
