I guess that the title isn't totally accurate because of course there is a reason, but what I mean is they haven't done anything THAT bad. Just generally boring conversation, not replying to messages, not an overall friendly vibe. I have a regular that I find myself dreading the classes a bit. They also complained once that they didn't feel like they were improving fast enough, so tried more challenging lessons but he didn't like them. Today I was about 90 seconds late for a class and he closed the lesson. My fault to be fair, but I had a wifi issue and had to reset it. I thought they were a little impatient here and I am tempted to block them. I just find all my other regulars have an easy and friendly vibe to the lesson that is missing here. What do you guys think?
