A Peep Through the Letterbox

I heard a cheery jingle from outside and scampered straight to the front door! There was a brass letter flap down low, gleaming in the hallway runner's soft shadow. I reached up on tiptoe, pushed the hinged metal plate with both plush hands, and let it swing open just a crack. Cool evening air drifted right in! Through the slot, I spotted warm porch lamps flickering on along the sidewalk and a neighbor strolling past with a bouncy terrier. The whole wide neighborhood is just waiting on the other side of this door!
