in Thoreau’s Journal:
I am invited to take some party of ladies or gentlemen on an excursion, – to walk or sail, or the like, – but by all kinds of evasions I omit it, and am thought to be rude and unaccommodating therefore. They do not consider that the wood-path and the boat are my studio, where I maintain a sacred solitude and cannot admit promiscuous company. I will see them occasionally in an evening or at the table, however. They do not think of taking a child away from its school to go a-huckleberrying with them. Why should not I, then, have my school and school hours to be respected? Ask me for a certain number of dollars if you will, but do not ask me for my afternoons.
