I Can See Crumbs

It is Thursday.

I have a magnifying glass.

Now I can see very well.

I can see crumbs on the floor.

I can see them near the window.

I look at the chair.

I can see a small hair on it.

Is it a cookie crumb?

No, it is not.

I can see footprints too.

I can follow them.

The footprints go to the shelf.

I look behind it.

I can see something dark.

What is it?

I cannot see it well.

I take my flashlight.

Now I can see it clearly.

I see a small space in the wall.

I can feel cold air.

I can hear a soft sound.

Something is behind the shelf.

I can find it tomorrow.
