... Monday. I was away visiting family when I received the email and I wasn't sure if they needed a confirmation as I had already expressed my availability and they simply picked a time that already worked for me. So when I did respond I mentioned how I was sorry for responding a few days late as I was visiting family and I also wasn't sure if they needed a confirmation on my end. Did I mess up? Or is it ok as I had already been in correspondence and I apologized for my tardiness and gave reason?
