RIDDLE

I sit waiting for you to arrive.
Many people walk by but i stood out to you.
You grip me so tight.
And flip me on my back.
And you stare as if looking for facts.
Spread me and let me take you on an adventure.
Or show you someone elses.
I represent someone else.
you will see all there thoughts, while exploring me.
If i interest you not.
Sit me down and Ill watch as you explore many others.
