No one can touch me

I am very fragile

Yet manage to break me

It's too late to realize

 

Every creature out there

Possess one of my kind

Some express freely

Yet many happens to hide

 

I have many identities 

Some fake, some real

Time and situation guides

The form i will appear

 

Many tried to control me

Yet utterly failed

For there are some moments

I succeeded to escape

 

I am the first

You are introduced 

When you are born

Out of my variations 

Which one do you adore?
