Let me use the last few sentences of Eric Clapton's song "tears in heaven" as an encouragement:
Beyong the door,
there is peace
And I know
there will be no more
Tears in heaven.
I agree life is so fragile, so short, and so unpredictable. but i agree that "there will be no more tears in heaven". may those of your friends who perish rest in peace and smile in heaven.
