I need a poem to read at a funeral....

A dear friend of mine has died and I have been asked to read a poem at her (non-religious) funeral. All the poems I can find are a bit over-sentimental. She was a very down-to-earth person with a sense of humour - very practical and fun.

Any ideas? I would be grateful for some help.

I need it to be fairly short, as I do not know if I will hold it together to be honest. It seems only 5 minutes since I lost my OH and was organising his funeral.
