I checked a couple of (English) books in my library, and all of them used single spaces after a sentence. Except for The TeX Book. (I didn't check other TeX-related books, but I guess they would do the same.) AFAIK, English is the only language that used to have the "double space after a sentence". To me (a non-native English reader), using 2 spaces in a monospaced text just looks weird. In a book, it doesn't distract that much.

In typesetting, there is no such thing as "two spaces". There is just space between words, and that space would be larger or smaller in order to justify the line. Some spaces (like the ones after a sentence) would be made larger or smaller to keep in line with special typesetting rules.

The concept of whitespace as a character didn't exist before computers, where it was needed to keep words apart.

You can get over being bullied. It just takes a lot of work. If you're bullied hard enough to be damaged, you will eventually understand you have a problem. When you finally search for help, you will notice there are dozens of therapists who are trained to deal with your situation.

On the other hand, bullies do not have a reason to change. They get a job and continue to harass the weaker employees around them.

Bullies don't grow up, they just grow older.

Belgium has an opt-out system. You can register on the site and then you won't receive any phone books anymore. (I just filled out the form, thanks to this article.)

I can't remember when I last used a full phone book: they're too large to find anything.

There is also a local business guide for each town. That one is small enough to be used, and it's useful whenever you need any service in your neighborhood (say, a plumber).

There's only one picture of what it looks like in a glass. No foam. So it's not beer.
