How do I tell a fellow student of Aikido that they are being both annoying and disrespectful and not be mean?

There is a kid in my Aikido class that I am usually paired with (due to height) that has been corecting me when he was no real reason to and no knowledge to back up the correction and has been ignoring some small but important rules of etiquette.What can I do to try and get him to stop besides ask my sensei? (I only bring this up because the rules being ignored are matters of safety)
