'O Tiger-lily,' said Alice... 'I wish you could talk!' 'We can talk,' said the Tiger-lily: 'when there's anybody worth talking to."
Lewis CarrollWhen I come upon anything-in Logic or in any other hard subject-that entirely puzzles me, I find it a capital plan to talk it over, aloud, even when I am all alone. One can explain things so clearly to one's self! And then, you know, one is so patient with one's self: one never gets irritated at one's own stupidity!
