"How are you?"
The most unadulterated answer to this question is:
"I'm fine"
After saying "I'm fine", no one asks, "Why?"
"Why not?" "What happened?" - All these hundreds of thousands of questions began to tingle !!
Sometimes I don't want to explain myself ... Sometimes I don't want to explain anything to anyone ... Sometimes it is not possible to explain anything to anyone ... So as I am, the answer is always "I'm fine !!" :)
