User talk:Ha i troll u again

October 2014
Hello, I'm Frosty. I wanted to let you know that I undid one of your recent contributions —the one you made with this edit to Timeline of aviation – 19th century— 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. —Frosty ☃ 22:33, 14 October 2014 (UTC)
