Terminator 2: Judgment Day

The Scene:

It's night. T-800 (the terminator - a killing machine) has just randomly shot and seriously wounded a thug who young John was teasing in the parking lot of a bar.

John: You can't just go around killing people!

T-800: Why?

John: What do you mean why? Cause you can't.

T-800: Why?

John: Because you can't, okay? Trust me on this.

The Thought:

When you are a hammer, everything looks like a nail, even a flower. If you're tired of 'nailing flowers' and getting the opposite results to what you're after, next time you encounter a nail try using your screwdriver.
