How I Know About Filter?

I never thought

That I was using filter before

But I was wrong

When I realize

I use filter every day.

I walked

East to west

North to South

With a fancy cloth

But I never realize

I was using filter

In school

I talk with teacher

Like a cat

Angry voice but yet soft.

With friend

I talk with them

Like a dog

Lout and angry.

In my home

I rear tank top and shorts

In an Interview

With suit coat, tie or bowtie

I never knew

That I was using filter

Until I realize by the way

I dress talk and act.

I never think dressing was filtering

Until I know without dress we will be naked.
