If I am holding a cup of coffee and I spill it, whether I do it or someone bumps into me or shakes my arm, it goes everywhere...
Now, why did I spill the coffee?
Was it because someone bumped into me?
Of course not.
I spilt the coffee because, it was in my cup...
If it was water or tea in my cup, it would have been water or tea I spilt out. Whatever's inside the cup will be what spills out. ...
