Character can be shown through the things characters do, what they say, what they look like, and what they own.
What do you find out about Crooks, the stable-hand in Of Mice and Men, from the extract below?
Crooks’ bunk was a long box filled with straw, on which his blankets were flung. On the wall by the window there were pegs on which hung broken harness in process of being mended; strips of new leather; and under the window itself a little bench for leather-working tools, curved knives and needles and balls of linen thread, and a small hand riveter. On pegs were also pieces of harness, a split collar with the horsehair stuffing sticking out, a broken hame, and a trace chain with its leather covering split.
Crooks had his apple box over his bunk, and in it a range of medicine bottles, both for himself and for the horses. There were cans of saddle soap and a drippy can of tar with its paint brush sticking over the edge. And scattered about the floor were a number of personal possessions; for, being alone, Crooks could leave his things about, and being a stable buck and a cripple, he was more permanent than the other men, and he had accumulated more possessions than he could carry on his back.
Crooks possessed several pairs of shoes, a pair of rubber boots, a big alarm clock and a single-barrelled shotgun. And he had books, too; a tattered dictionary and a mauled copy of the California civil code for 1905. There were battered magazines and a few dirty books on a special shelf over his bunk. A pair of large gold-rimmed spectacles hung from a nail on the wall above his bed.
