I received a dinner invitation on my answering machine from a friend I generally see every few months. It was to be at her home in 21/2 weeks. As I was away when the message was left, I returned her call about 4 days later once I was home. I reached her answering machine, expressed my apologies for the slight delay in responding and also gratitude and acceptance for her invite. This was about 12 days before the dinner date. I said I would call again within a week to speak to her personally. Exactly one week early of the invited date, I received a message expressing the time she was expecting me to arrive THAT night! A second message to my cell phone a few minutes later, expressed her confusion as to whether she had invited me that evening or a week later. But that I was welcome to both, as she apparently was hosting two different parties. It was weird but I called and verified that I had been invited to the later dinner and apologized (?) for not being available this evening. During the conversation, she definitely sounded distant. I feel really weird about the invite at this point and not sure how to handle next week's dinner invite. Any suggestions or thoughts on what is going on?
