There’s always a little truth behind every “just kidding”;
A little knowledge behind every “I don’t know”; and
A little emotion behind every “I don’t care”.
We often say things we don’t mean. In other words, we say something and mean just the opposite. There are various psychological reasons behind it. We are actually hesitating to share our innermost feelings. We are afraid of ourselves, so to say. We don’t dare to be honest even with ourselves.
