IMAGINE by Emel

                                                "Imagine" by Emel Nur Er


Imagine there's no school,
It's easy if you believe.
No burden below us,
Above us only fun.
Imagine all the students,
Living the moment.

Imagine there's no homework,
It isn't hard to dream.
Nothing to stay up or cry for,
And no grades too.
Imagine all the students,
Having fun everyday.

You may say I'm a dreamer,
But I'm not the only one.
I hope someday you'll join us,
And the students will be free.

Imagine no examination,
I wonder if you can
No need for crying or whining,
A happiness of the students.
Imagine all the students,
Singing songs 'til midnight.

You may say I'm a dreamer,
But I'm not the only one.
I hope someday you'll join us,
And the students will be free.
