Yes, there's an ego which wants to get better and is worried when their teacher, which has helped it a lot in the past years, starts showing obvious signs of unawareness and unhappiness.
But should we just use the awareness of that story to stay blind to the content of this post? There's definitely a problem. Without doubt, complaining about it here is probably a worse solution that distancing ourselves from the teacher and finding more sources of information, new teachers and practicing ourselves. Yet it is painful to think of Leo in his current state, especially when it's Leo who taught me to avoid the traps he seems, from my limited judgemental point of view, to be falling into.
