Well, again no offence, but I like to work with smart people. Bad grammar does not scream “smart person”, it screams just the opposite. In case you are not sure what I am referring to: “apart” in the title should be “a part”, “Me and my cousin” should be “My cousin and I”, you do not use a single period to divide your paragraph into sentences, etc.
Now I’m no genius when it comes to grammar, but there is often a correlation between bad grammar and other bad areas of a person’s personality, in my experience anyways.
