Not Quite Written in Stone

Black, blue, red, and green, You can write whatever you please. But when you use a tool with no eraser, you run the risk of regretting it later. Please be careful, Because your fate could be determined by just one mistake. Let out your emotions, your wishes and woes, but know anyone could read them- family and foes. So putting thoughts down in elegant ink might come with a higher price than you think, Watch what you write, and think who might get into it, Because once it's in ink pen, You can't undo it.
