'Normal' and 'Perfect'

What is the definition,

Of perfect and normal?

Perfect, flawless,

Normal, same as everyone else.

Yet, everyone is always saying,

"Nobody is perfect, everybody has flaws"

And 

"We are all different, nobody is normal"

So why, how, did all of a sudden, 

Everybody start using those words?
Normal and perfect, both words that sting,

The main words used by bullies.

Aren't perfect and normal,

Just words created, to put others down?

The world is starting to accept others for who, 

They truly are.

Yet the words remain, and will forever remain,

In the dictionary, on the internet.

Because the words are proven legal,

Nobody wants to erase it. Why?

Perfect and normal, are words that aren't real.

Yet we refuse to erase them, why?

For eternity yet to come, 

Nobody is brave enough, 

To erase the words from memory.
