Who is Slim? Describe his appearance and character in chapter 2.

In terms of his appearance, Slim is described as a "big tall skinner." He has a "hatchet face" that is "ageless," and hands are "large and lean . . . [and] as delicate as those of a temple dancer." Slim's eyes are described as "calm [and] Godlike." Slim also moves "with a majesty achieved only by royalty," implying that he moves gracefully. In many ways Slim has a typically masculine appearance. He is broad and tall, with large worker's hands. However, there are also aspects of his appearance which might be described as typically feminine, such as the graceful way he moves.
In terms of his character, Slim is described as a "Hell of a nice fella" and as "the prince of the ranch." He has "a gravity in his manner, and a quiet so profound that all talk stop[s]" when he speaks. His authority is such that "his word [is] taken on any subject," and his opinions are regarded as "law." Slim is also kind, as demonstrated when he offers a puppy to Lennie. He is not at all judgmental, as demonstrated by the way he interacts with Crooks. Slim becomes somebody that George can confide in. In chapter 3, Slim asks George about his relationship with Lennie, in what Steinbeck describes as a "calm invitation to confidence."

In Of Mice and Men, Slim is introduced to the reader in chapter 2. In terms of his physical appearance, Slim is tall, with long, black hair that is brushed straight back. In terms of his age, it is hard to judge. He has an "ageless" appearance, meaning he looks anywhere from 35 to 50 years old. Like the other men on the ranch, Slim wears blue denim jeans and a denim jacket. He also wears a Stetson hat.
On the ranch, Slim is a "jerkline skinner," meaning that he drives a team of mules. He is well-known among the men for his strength and skill.
When it comes to his speech, Slim speaks slowly, but this is not because of a lack of understanding. In fact, according to the text, he understands "beyond thought." Moreover, when he speaks, he has an air of authority. The other men always listen to him and accept his word as final.
In terms of his character, Slim is friendly and "kind." He gives a warm welcome to George and Lennie, for example, and he shows a genuine interest in George and Lennie's past, particularly how they came to be together. He also introduces the men to Carlson, a sign that he is keen to welcome them into the ranch family.
