I Have Pet Peeves

I by far am not perfect when it comes to using the English language, however, I do have a major pet peeve when it comes to someone starting a conversation or answering a question.
If the first thing out of your mouth when starting a conversation or answering a question is "I mean" then you look like an idiot to me. Making that comment implies that you had already said something that needs clarification. How could something need clarification if you had just started speaking and that was the first thing out of your mouth.
