you will need to find a source that your quoting.... You can quote a verbal conversation that you where a part of, but if you weren't there when that was said, you need to cite a source. Also, if it was written you need to quote it from the source. In formal writing you have to lend credibility by showing where you got that source from. Some teachers that are not picky will let you cite it like you did in the essay, but you still have to show where you got it from in your references at the end of paper and the way you have it written above will not be an APA reference format.
