I Shouldn't Have Done That

Last week, I was at the grocery store and noticed my friend Sally had left her wallet on the checkout counter. I figured she'd be back to pick it up soon, but with a bit of curiosity getting the better of me, I took it home. It's just sitting in my drawer, I haven't opened it or touched anything except for making sure there was enough cash inside to cover what Sally might have been buying. Now, every time I see it, I feel a knot in my stomach. I really need to return it, but the thought of seeing her makes me nervous.
