Hello, I'm Lugia2453. I wanted to let you know that I undid one of your recent contributions, such as the one you made to Drag (physics), because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks, Lugia2453 (talk) 23:13, 12 November 2012 (UTC)
