Take it easy with criticisms
Criticism is a form of unconscious competition.
It means that you’re trying to find a soft spot in someone’s armor, a point at which you can fight him unjustly and win.
Even if your intention is good, it may seem an attempt to pull yourself up by pulling him down.
Most people are sensitive; they can’t accept judgment right away and they take criticisms personally.
So, take it easy. Think before you speak.
