Morpheus: Do you want to know what is the Dark Side, Neo?

Neo swallows and nods his head.

Morpheus: Unfortunately, no one can be told what the Dark Side is. You have to see it for yourself.

Neo: How?

In Neo's right hand, Morpheus drop a red pill in his left, a blue pill.

Morpheus: If you take the red pill, you will join the Dark Side. If you take the blue one, the story will end. After this, there is no going back.
Remember that all I am offering is the truth. Nothing more.

Neo opens his mouth and swallows the red pill.

So... are you brave enough like Neo, to join the Dark Side?
