Never mind,I hope I won't make much spelling mistakes on this.
Why would I label it this way? Because from what I've seen, many
people behind the computers always have this particular fantasy
when chatting with ther other party. In their mind, they like to
create a perfect world of the other party, be it they are pretty,
intelligent or might be able to fulfil what they have lack in
reality. But when they come face to face, they realise that their
fantasy might not be what they expected in the cyber world.
Disappointments and heartbreaks, that's what I could conclude when
they are facing each other.
