Pardon?

I'm pretty sure I have this weird habit... when a member of the general public, sometimes even people I just don't know very well, say something to me or ask me a question, I always say 'pardon?' regardless of whether I've heard them or not.  Sometimes I even catch myself saying it and think 'why the heck am I saying this?' but I still do it.  Maybe it has some huge great significant meaning.  Maybe it's nothing.  But it's what I do and I don't plan on stopping.
