`  :You want the linguistic break down? ``Don't`` - Contractional variant of ``Do not``, an imperative command. ``Mess [around]``, an intrasitive verb, is commonly used as a colloquial expression for ``creating a disorder``; this automatically implies that you are assuming people will mess around with it. A more neutral, less imperious substitute would be: ``Please do not edit my sandbox`` - Instead, you chose something that automatically assumes bad faith. You didn't say ``please``, or ``thank you``... you just wanted to seem like the big alpha male who controls a whole sandbox! By the way, you'll never own anything on Wikipedia. You own nothing on Wikipedia. Either be polite and calm or go elsewhere to be controlling, aggressive, and dominant. Thanks.  `
