The leash goes slack
The horse knows when I'm grooming him.
I don't know, but if you see it, RUN!
Just one. But he will pull it back out and stick it back in again just to make sure hes got the right hole.
Once in a blue moon.
A short one!
A: The leash goes slack.
He felt the slack in his dog's leash.
Because they're poor conductors! (I know they're called Engineers but cut me some slack, I thought of this in the 9th grade.)
