Rosa is introduced by Daniel. She appears in a photograph taken in December 1942, when Daniel was 15 years old. When Erika brought Rosa home for a visit, he met her. Daniel is sitting in his underpants while his clothes is being deloused, and his family laughs at his embarrassment. They went on a date to the movies, had dinner together, and then walked in the park. They talked about many things including religion and politics. Daniel liked what she had to say and decided he wanted to be with her. However, they knew their families didn't approve so they didn't tell anyone about their relationship until after the war when restrictions on dating were no longer enforced. During this time period, German soldiers were stationed in both Poland and Russia, so many girls were available to date. When it came to choosing someone to marry, most young men chose based on status, money, or position rather than love. But for some young men, such as Daniel, the idea of marrying for love first entered their minds around this time. After hearing rumors that Rosa wanted to marry him, Daniel's father agreed to let them get married if Daniel's mother could travel to southern Russia to meet Rosa's parents. According to custom at the time, Daniel's father needed to give his permission for the marriage to take place. When Daniel's father agreed, they set a date for January 13, 1943.
