My close friend Makiko got involved in a multi-level marketing scheme I introduced to her and ended up burdened with massive debt. She kept the debt a secret from her husband and, unable to bear the suffering, took her own life. I was indirectly responsible. Filled with guilt and a sense of responsibility toward Makiko's husband and son, I began visiting their home daily, helping with household chores. Over time, Makiko's husband, overwhelmed by grief and loneliness, began directing his sorrow toward me. His pain and isolation deeply stirred my heart.
