It sounded as she did comment about the meeting. And it also sounds that she replied to your original text when you informed her about the meeting. You said you texted her about the meeting and she commented on it. I am not sure what questions she didn’t ask. Like more questions about the meeting?

I am honestly failing to understand where she went wrong by just being polite and appropriate. You said she isn’t a friend but just someone you know.

So maybe her responses lacked warmth but is it how she always talks? I have a friend who I actually consider a friend and she has this weird way of texting (she NEVER speaks like this in person or on the phone, only in texts or emails) she responds to a lot of info with “I am glad to hear it” or “I am sorry to hear it”. She just retired after 35 years as a lawyer and I sometimes feel that she is cautious in written communication because she got into a habit of it for professional reasons. She is way more personal in person

So I am not sure if this lady truly didn’t care or just responded in the way of how she communicates?
