Hi there! Drawing a simple line in Word 2003 is actually pretty easy. Here's how you can do it:

1. Click on the "Insert" menu at the top of the screen.
2. Select "Shapes" from the drop-down menu.
3. Choose the line shape you want to use (either horizontal or vertical).
4. Click and drag your mouse on the document where you want the line to appear.
5. Release the mouse button when the line is the desired length.

If you want to make sure the line is perfectly straight, hold down the "Shift" key while you're dragging the mouse. This will constrain the line to a straight horizontal or vertical direction.

Once you've drawn the line, you can customize it by right-clicking on it and selecting "Format Shape" from the drop-down menu. From there, you can change the color, thickness, and other properties of the line.
