Last week, I had lunch with someone I've known through work for a few years .
As our offices are just one block away, we have lunch together from time to time (maybe once or twice times a year).
She is smart and quite nice. But her behavior and the way of talking make me slightly uncomfortable.
As I saw her last week, I greeted her in a enjoyable tone with a big smile but she didn't watch me in the eyes and was nonchalant.
Usually, when you talk with someone, you space your words to assess the reactions of your counterpart or to give him/her a say when needed. But she never let me any moment so that I ask her a quick question or give her reaction words something like that.
Anyway, as the lunch was her treat, I feel an obligqtion to buy her a next lunch. Afterwards, I'll see if I keep mingling with her.
