User talk:Beant S Grewal

December 2012
Hello, I'm Calvin 1998. I wanted to let you know that I undid one of your recent contributions, such as the one you made to Urinalysis, 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, Calvin (t·c) 06:36, 31 December 2012 (UTC)
