Decode this comment from a Cap co-worker

I was at a casual get together for a co-worker who is leaving town. To simplify, we all work for the same person but at different locations. I don't know the Cap, just met once very briefly, and she's not the one leaving.

There were 2 Virgos, 1 Gem, 1 Cap, 1 Sagittarius.

After the dinner, the Cap says to the person that we all work for that I "seemed quiet".

This comment is inaccurate as I talked a lot to the Virgo and Gem (the one leaving). Actually, the Cap seemed quiet and anti-social - going out for cigarette breaks by herself and coming back smelling like smoke while people were still eating. It was kind of rude tbh.

What is the deal with this comment? Am I obligated to talk to her? Why doesn't she talk to me if she wanted to have a conversation?

She is a Jan 18th Cap.

I honestly don't see anything wrong with the comment at all, even if you felt it was inaccurate. It was just her observation. People tell me I seem quiet all the time. *shrugs*
