Offended? Me?

So my boss is writing up this proposal. He came by and said to me "You are a technologist, right?" and I said "no, I am a Scientist." He stood there for a minute, and said "What level scientist?" and I said "associate" (a couple levels above technologist--maybe 2 or 3?).

He said "Hmm. Well, for this proposal, I have written throughout it that you are a technologist. So, for this project, I guess you will be considered a technologist, because I'm not re-writing it all at this point, ok?"

So I said ok. But, is this really ok? I mean I don't have issues with being mistaken for a tech, I mean, that doesn't mean that much. The issue I have is that MY BOSS DOESN'T KNOW WHAT MY JOB IS. That bothers me. I'm his only employee. He does my reviews. He hired me. He promoted me.

If someone else had made the mistake, no problemo. But I wouldn't expect him to make that mistake. Especially with only ONE employee.
