During a race a few years ago, the arm stopped working during a race and the dogs caught up with it and started ripping at the decoy. Realizing it was fake they stood around confused. Many of the dogs could never race again because they knew the decoy was a fake.
I think we have some similarities to their experience. Sometimes we think we're chasing the proverbial rabbit when it isn't real and we don't realize it until we catch it. Maybe it's chasing that dream car or home and when we finally get it we realize it wasn't as fulfilling as we'd expected.
The devil puts shiny things in front of us hoping we'll get distracted and start chasing it while we're leaving behind the things that really matter. The bottom line to my post is look out for decoys because they're not always what they seem.
