Probably most of us have those, things they dislike, instantly and strongly, for no obvious reason. One of mine is hearing someone say "inner-resting" for "interesting". I don't know why it grates on me so. I know what the spoken word refers to, so it's not because I'm asked to work on getting it. I just find it as irritating as long nails scraping on a blackboard.
Sometimes these odd dislikes have to do with half-forgotten childhood events, though not in the case described above. And yes, this is a totally pointless post. Totally pointless posts are the new fashion in blogging.
