Nevermind

Nevermind...

Never mind... What a great word. 
 

It can be kind and considerate... no worries... forget about it. 

Or

It can be sarcastic and dismissal... go away... I can do it myself.

And the best part... if used skillfully...

Others will never know which way you meant it. 

English... Such a great language. 
No doubt adapted by Americans.

And used to its greatest potential.
