I was teaching a friend of mine how CSS works for her exam and we reach the point where she had to style the tables and she reads:

To avoid having spacing between table cells you can use:
border-collapse: collapse
[...]
border-collapse can also have value "separate"

She fucking freaked out like "WHAT THE FUCK IS EVEN THE SENSE OF IT? SHOULD I HAVE BORDER SEPARATE: SEPARATE? WHY THE FUCK SHOULD I WRITE THAT TWICE? HOW THE FUCK DOES THIS EVEN WORK OUT?"

I just loved how she doesn't know how to make a website but she already hates CSS before even using it on an actual browser
