Aware by Denise Levertov 

 When I opened the door I found the vine leaves speaking among themselves in abundant whispers. 

My presence made them hush their green breath, embarrassed, the way humans stand up, buttoning their jackets, acting as if they were leaving anyway, as if the conversation had ended just before you arrived. 

I liked the glimpse I had, though, of their obscure gestures. I liked the sound of such private voices. 

Next time I'll move like cautious sunlight, open the door by fractions, eavesdrop peacefully
