The pig and the wolf

We can't honestly say We didn't intend it this way, We gladly erect Our houses of hay And of twigs and sticks From the forests we pick We construct flimsy structures That fall with a kick These walls we raised, We raised to fail Barriers built With bricks beyond frail The mortar beneath Diluted and porous The grout In between Never stood strongly for us We huff and we puff And we blow it all down And bask in the light Of the love that we've found We're not afraid of the world, you see I am your wolf And your piggy is me.
