How are modern monsters hidden from us, and why does this make them especially frightening?

See explanation:

Explanation:

When you say the word "monster", you immediately visualize big furry giants with horns and large teeth. And perhaps they might have existed in the oldern days, who knows?

But today, its not those giants that are the real monsters. The real monsters are the people who are around you every day.

You talk to strangers on the internet. You come across people on streets every single day. You don't know if they're angels, or serial killers.

You might be pleased with someone's face and wealth, but you don't know what they're hiding underneath.

The scariest part is, those monsters can be anyone. It can be your friend next door, or even your best friend. You never know what they're hiding under the mask.
