“I felt great and was good at criticizing others.”
Especially friends; a token of appreciation – caring enough to give tips for improvement, tips disguised as pointless condescension and hurtful insult.
[Improvement by what standards? Mine. My ideal. Falling back to absolutism.]

In direct tones – that may have sharp edges and exposing harshness – it is easier to express what one feels. It should really be seen as appreciation when I insult someone’s things and action; it means I take the time to think about them and their things and voice my opinion directly.
