Removing Permanent Marker on Whiteboard

I love writing on a whiteboard, especially if my boss always had an errand for me, or for his schedule of meetings, but one thing that I forget is the difference between the permanent pen and the whiteboard pen, because I always end up picking the permanent pen.

So to erase the permanent pen on the whiteboard, you can only use one step. All you have to do once you have already used the permanent pen, just overlap it with the whiteboard pen, so that the permanent pen will erase. That's so simple!
