Leaving out comments assuming your code is readable enough. Code != English

The code was hard to write, so it should also be hard to read...

You can just add them later

@Conrad hahaha. That's what the author of that uncommented code says. Then he/she leaves the company.

Code is indeed not English, code can be read just one way, english can have two meanings where one is meant.

In addition to the previous comment, how do you expect someone that can't write self explaining code to write good documentation? That might sound irritating at first, but I personally prefer short and descriptive code rather than long and messy code with a lot of documentation.

@Rethought until you work on a project existing for 12 years, which takes 8 hours to completely download from a local source control system.

Its so huge and complex that a bit of documentation would be handy.
