Erika is Brian’s little sister. When they were younger, Brian loved to torment her. For an assignment early in elementary school, Brian illustrated a story of him defeating her in a karate competition. As they’ve both matured, they’ve grown to enjoy each other’s company, even spending two weeks with both her siblings jaunting around Europe together. Now, they love going on walks in brisk Chicago weather to neighborhood coffee shops whenever Brian comes to visit. Brian is delighted to be able to share his special day with her.
