So, a weird thing just happened.

I have a pack of sliced bread that says 12 slices on it. Whenever I make a sandwich, I usually use 3 slices, with one bread in the middle simply because I want more.
I have made 3 sandwiches so far, and I just ate 3 more slices (individually, not as a sandwich). But, there's still one slice left for some reason? It's the crusty end cap, which by the way, there's only one end piece in the whole bag instead of two.
