In the novel The Outsiders, how did Sodapop react when Mickey Mouse was sold?

In Chapter 3, Ponyboy is having a conversation with Cherry, and he begins to talk about Sodapop's horse, Mickey Mouse. Pony tells her that Sodapop had a dark-gold buckskin horse that wasn't his but belonged to a guy who owned the stables where Soda worked. He explains to Cherry that Soda was absolutely in love with the horse, and Soda would visit him every day. Ponyboy says that Mickey Mouse was ornery and would continually kick the other horses. Even though Mickey Mouse belonged to someone else, he was still Sodapop's horse. When Cherry asks if Soda still has the horse, Ponyboy tells her that Mickey Mouse was sold. Ponyboy explains that Mickey Mouse was a valuable horse, and Sodapop was devastated when they came and took Mickey Mouse away. Pony says that all Sodapop ever wanted was a horse, and he bawled all night long the day Mickey Mouse was taken away. Sodapop kept his feelings to himself because he understood that his parents were not wealthy enough to buy Mickey Mouse back from the people who had bought him.
