He stole my idea

I had a great idea for streamlining some of the tasks that we have to do as part of our everyday testing. It involved using standardized automation tools to automate some of the more repetive tasks that we have to do often. Just when I was starting to get some traction in getting it all working right another co-worker (the one with his own office for naps) started putting it down in front of my manager and said that he could right a better tool using Python. Can you believe that?
