Hello, I'm Kvoou. An edit that you recently made to Two-factor theory seemed to be a test and has been reverted. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. --Kvoou (talk) 07:53, 15 June 2022 (UTC)
