If you write, you may embark on a series of stories or poems. Your school or place of worship may allow you to build a memorial garden. Working in the earth can be therapeutic, and planting can express hope in the future. If you do build a garden, be sure that someone makes a commitment to maintain it. Weeds and neglect do not make a good memorial.
Anger is a form of energy.
You might organize a group to promote awareness of the condition that caused the friend s death. You might organize discrete rides home for classmates who become intoxicated at parties. Celebrating and commemorating a friend s life may not mean that you agree with the way he died. Seeking to understand someone s reasons for drunk driving or suicide is not the same as condoning a self-destructive act. Finally, your own life can be a memorial.
