The funeral

My friend has died after a short but very maligne illness called brain cancer.
I have been to the funeral where the priest told us that she wouldnt like us to be unhappy about her death and that we should rejoice and be happy.
Well, Im not quite sure if I can do that for her, and Im pretty sure that its good that she was released from her suffering so quickly, but its very sad and somehow disturbing.
I will miss her dearly and also her strange sense of humour!
