When you touch me, you get the shock,
When you read me, you get a dear pal,
When you control me, you get a true servant,
When you step on me, you may fail to breathe.

When I am with you, you feel cold and warm,
When I am with you, you are happy and strong,
When I am with you, you can play and seek fun,
When I am with you, you can see the heart and brain.

When I am gone, you may get stuck and cloudy,
When I am gone, you open the curtain to see the sun,
When I am gone, you are restless and full of fear,
When I am gone, you don't know how to live with fun.

You and I are inseparable, as you need me, not I need you,
You and I are in agreement, written for you, not mutually,
You and I have become the slave and masters,
For I have to run lovelorn millions of kilometer.
