Writing Exercise: An Epic Door Poem

There is something about this line, this invitation or instruction. As you might know it’s the first line of The Door by Miroslav Holub. He writes: Go and open the door./Maybe outside there’s/a tree, or a wood …/Go and open the door./Maybe a dog's rummaging… Read the whole poem here. And write me a ‘Go and open the door’ poem or stanza or just a line - we could write an epic (inspired by Cordite). How would we do that on blog? You all reply and I'll collate and post periodically. (There's probably a better way but hey...)
     I'm interested in doors. One door closes, another opens. Sometimes I take photos of them.
