I hate it when people say stupidest. It is not correct. You learn this every year in Language Arts. It is most stupid or you replace it with a word such as dumbest. You can ask you Language Arts teacher or parent. When people say ain’t, I get depressed. Ain’t is in the dictionary, but it is defined as a word for isn’t used mostly by southerners or incompetent people. So please, I beseach you use proper grammer when speaking.
