Me whats the secret? we have a secret, just we three, the robin, and i, and the sweet cherry-tree; the bird told the tree, and the tree told me, and nobody knows it but just us three. but of course the robin knows it best, because she built the—i shan't tell the rest; and laid the four little—something in it— i'm afraid i shall tell it every minute. but if the tree and the robin don't peep, i'll try my best the secret to keep; though i know when the little birds fly about then the whole secret will be out.

Hi! :)

Wow that was sure challenging! But after reading the poem over and over again, I have concluded that I think the secret that the robin and the narrator and cherry tree are keeping, is that the robin made the tree. The reason why i believe so, is because the robin said she knows the secret best. The robin was the first to know and then told the tree. The robin must have built something for it says , "Because she built the—I shan't tell the rest; And laid the four little—something in it—" and Then say,"Though I know when the little birds fly about Then the whole secret will be out." So I assume the bird must have built maybe a hole into the tree for it to fly out of? I apologize if this does not make sense, but this is what I think the secret is!
