Dumb, easy hypothetical

[Roybert]

I'm sorry to bug you guys with a stupid one, but I want to know what I should do in this hypothetical situation. Sorry in advance if this one is more suited for the beginner forum, too. I would post a hand, but I don't have one to post (it was just something I was thinking about).

Say you have a nut four-flush on the flop. Someone leads out and you are second to act. Should you raise or call generally in this situation?

I know that there are a lot of other factors to consider, but i am just curious on what to do in a typical micro-limit table.
