I concur with the good advice here and above (sorted by top comments). Be Christlike but cautious and do everything out in the open. Treat the person with respect, give no reason for suspicion to arise, and don't let anyone bait you. Focus on getting the work done so you can get your good grade. You're right - this is the kind of thing liberal "educators" often pull to make their point - but don't get caught up in their hang-ups.
