'Unfortunately, that's not John, but his second self.'

”I love you. I am happy with you. But I love her too. I’m this person when I’m with you but I also feel different when I’m with her. It’s like I’m two different person”.

Have you heard of this? Absurd right? You think it happens in real life?
We might have watched it over a sappy movie during a Saturday night or might have read it from a fiction book.

It is commonly used to describe a person who is significantly different in his moral character from one situation to the next.
And someone who has a split personality.

The term came from a novel by Robert Louis Stevenson with the title, Strange Case of Dr Jekyll and Mr Hyde.

A more subtle real life scenario is how you can smile and agree in unison with someone yet say nasty things behind their back.
So would you say you’ve been a Jekyll and Hyde to someone lately?
