Where you write with a pen.
a space pen
I don't see why you would not be able to write with a pen in space. Pens operate on the principle of capillary attraction, and that is not affected by gravity or the absence of gravity. The only issue I can see is that if you attempt to use a pen in a vacuum, any air bubbles contained in the ink would expand, and the heat of your hand might make the ink boil.
Well the ink comes out of the pen and that goes on the paper and if you are not an idiot you can write words.
You CAN write in space. With a chalkboard and eraser or with pencil and paper. The problem is that in the vacuum of space, the liquid ink of a pen evaporates too quickly and dries out the pen. Additionally, within the pressurized crew compartment of a spacecraft, there is no gravity that is needed to cause the ink to "fall down" onto the ball of a ballpoint pen. To solve this problem, NASA solicited the design of a special ballpoint pen that could write in zero-G or upside down. The result was a pen with an ink cartridge pressurized with nitrogen, which would force the ink to the ballpoint even when inverted.
