This monkey hangs on the inside of my office door as a simple reminder to team members that stop by to visit. 

Please don’t leave YOUR monkey on MY desk. 

In other words, feel free to come talk to me if you want to discuss ways to handle a problem you’ve uncovered. But don’t come just to complain. If you want to tell me about a problem, be prepared to tell me how you can help resolve it. Don’t just leave it on my desk.
