Occupying the time.... Of a cow

They stand in fields.

They stand up.

They lie down.

They eat some grass.

Something's happening that we're not aware of. They're doing something else. They're playing I spy.

Cow1: I spy with my little eye, something beginning with G.
Cow2: Grass.
Cow1: Correct. Your turn.

Cow2: I spy with my little eye, something beginning with F.
Cow1: Field.
Cow2: Correct.

And so on.
