Well, just as I thought...she just called, has to skip the yoga class because she is running late due to unforeseen circumstances (send-off party last night for a co-worker, had to leave car at work). She is also not spending the night. Arrgghh. I said "that's fine, no worries, I understand". She said she needed to do some grocery shopping and she would be here after lunch. I ended the call with an "OK, I'll see you after lunch then".
So I thought about it and decided to go on the defense. I called her back and said "would you rather just take the weekend off and not get together? I'm totally fine with that. I don't want you to feel that you need to come over just because you said you were going to".
She said "no, no, I still want to come over, I just can't make it in time for yoga".
