'I mean, what is an un-birthday present?'
'A present given when it isn't your birthday, of course.'
Alice considered a little. 'I like birthday presents best,' she said at last.'
You don't know what you're talking about!' cried Humpty Dumpty. 'How many days are there in a year?'
Three hundred and sixty-five,' said Alice.
'And how many birthdays have you?'
'And if you take one from three hundred and sixty-five what remains?'
'Three hundred and sixty-four, of course.'...
'...and that shows that there are three hundred and sixty-four days when you might get un-birthday presents —'
'Certainly,' said Alice.
'And only one for birthday presents, you know. There's glory for you!'
From Alice Through the Looking Glass by Lewis Carroll
