My boss likes to measure the spacing between DOM elements using a ruler to make sure everything is proportional.

I forgot to remove some padding on an element so it wasn't exactly centered, so he comes in and says...

"the padding on the site is off, I think you need to use this" *drops ruler on desk*

Now I have to keep this stupid ruler on my desk because whenever I forget to align something he says... "that's why I gave you the ruler"

Too difficult to explain to these subhumans that I don't need a ruler to write proper css
