a poetical response following close observation: pebbles for rivers of stones
Good job it wasn't a murder of crows!
Dammit, I KNEW there was a more appropriate word but could only think of a parliament of owls ... now I don't know whether to be grateful to you for reminding me or cross because I could have done this better!
Ah - sorry. Collective nouns are one of my pet projects. I know loads. Have books of them in fact. It's fine as it is. I loved this - because it relates so well to the actual terms.
This made me chuckle!
