I'm supposed to be very busy at work. But I've really got to sneak this in:

Someone just called me 梁美贤 老师 (Liang Meixian laoshi)。

Yes, he got the name right, but 老师?

That person happens to be a professor.

I'm so damn embarrassed I don't know how to correct him. If I'm the 老师 of a professor, what does that make me?
