Stowaway in the Canvas Cave

I dropped straight through the open zipper into the deep belly of that canvas backpack! The inside smelled like woven fabric and mystery. Right near the bottom, I scrambled over a bumpy bundle of spare pens and landed beside a smooth, metal travel water bottle. It was propped on its side like a cool steel pillar. I wedged my boots against the canvas lining and braced my back right against the cold metal cylinder to keep steady. The bag shifted as someone picked it up by the straps, swaying like a wild ride! We're finally heading out into the real world!
