Peter and Manuela met in their high school senior year psychology class. They sat near each other and were often partnered during class discussions and group work.

They were both on the swim team and often volunteered at the same homelessness prevention shelter. By the end of the year, they became good friends. Later, Manuela and Peter attended the same college, and after graduation they became engaged. When they attended their five-year high school reunion it was obvious to their friends from high school that they were a very happy couple.
