I did not send save-the-dates to anyone. I work in a small office where most people I've known for over a year. I was talking to my coworkers about my wedding and mentioned I'll invite them all. Unfortunately, I wasn't being careful (obviously, big regrets now) and one of the newer employees (only working for about 4 months and not directly with me) overheard and assumed she will be invited as well. I barely know her, she is not in my age group, and most other co-workers find her annoying. I never directly told her I'll invite her.
Last week, she asked me when the wedding is. She told me she was very happy that it's on a certain day because otherwise she would have been out of town. I just smiled along and didn't know what to say.
Would you say I should invite this woman?
