Circuit Analysis: Current flowing from negative to positive?

Homework Statement

I am to write KCL equations for this circuit. Why is it that the current flowing AWAY from Node C is written as V2(t). I thought that when a current was flowing AWAY from a node, the current would be -V2(t)??

The Attempt at a Solution

My guess is this.

Normally a current flows from + to -. If this is true then:
> Current is negative when flowing away from a node and positive when flowing toward a node.

Unless the polarity is switched (like it is in the circuit diagram in which case, the sign if the current is switched? But i don't know if this is true or not. can anyone confirm or deny this?

It would be helpful if you would show the circuit you are talking about.

Just listing an entire website is not helpful
