Shame on you for having signs they could pick. Shame on them for making it obvious they were doing it. Shame on you for not using that information to your team's benefit. They gave you a gift. You weren't experienced enough to say thank you and open the package. Everyone who answered you so far is right including Bill. Your answer to Bill mirrors the way you handled the on the field situation. More b>))$ than brains. If you aren't going to accept the real world wisdom you are given then I'm not surprised you didn't accept the gift the other team gave you when they made it obvious they were picking your signs. Get your ego and temper out of the way and maybe you can handle it better for your players next time.
By the way, Mike has now explained how to accept the gift they offered you.
