Good morning or on your left are both OK with me- I appreciate knowing your coming around me.

If I am yo-yo'ing with someone who is not riding like a jerk I'll sometimes chat. I find pulling up next to them and asking a question about their bike is a good ice breaker.

I could care a less about being passed. I ride my pace and don't care about the pace anybody else rides.

I ride 41 miles RT 5 days/week year round so through sheer repetition my pace is rather brisk. I come across many who obviously don't like to be passed and will either speed up as I come up behind or try to suck my wheel after I go past. Those are really the only two things that annoy me.
