First, I bet the respondents are men. Second, I met with him and that's exactly what he meant.

I am a first year masters student in an urban planning program. I emailed my professor to request discussing the reading after missing a class. His initial response was yes, set a time. I then accidentally messaged him a thank you meant for another professor. He messaged me with ???? and I appolagized for the mix up and set a time. He then responded with this.

"4:30 pm is fine as long as the mewing needs are brief. I leave at 5:15 pm sharp for a southbound train."

I looked up "mewing" and it is defined as--" a cat or some kinds of bird) make a characteristic high-pitched crying noise.
"a throng of cats and kittens mewing to be fed"

This was Wednesday. I haven't responded and I have class with him on Tuesday.

What to do?

I am a female student and he is a male professor. He has also asked me in office hours before how old I am.
