[Matt Q]

I’m looking for a poem that I could read at the wedding of my sister and her girlfriend. So that's a poem about marriage, love, commitment etc. that’s not exclusively heterosexual, can be read by a third-party (i.e. me) – so probably not poems that directly address the beloved. Also, it can't be religious (this is a legal requirement of a registry office wedding, apparently)

Any suggestions would be welcome.

Many thanks,

Matt
