Reading passage

Read the following passage:

     "Rudy never talked much about his time in the Navy. He didn’t want his kids to pick up his pessimism. He’d joined up right out of high school, half excited to get out of the Chicago neighborhood he’d grown up in, half scared that he wouldn’t be coming back.

     "By the time he went to sea, the atomic bombs had dropped and the war was all but over. Even though he never saw any fighting, his time in the service still left him scarred. The everyday racism and petty cruelties directed down the chain of command made him realize there wasn’t much of anything noble about his service."
