Single space after a period at the end of a sentence
A good way to measure the generation gap.
Those people who learned to type on a typewriter had 'typing two spaces after a period at the end of a sentence ' beaten into them by frustrated old maids with licorice on their breath.
The kicking and screaming introduction of
WYSIWYG (the first virtual reality) combined with word processing's in-built automatic kerning revealed just how gaping a hole those two spaces gave:
"Hey! That looks funny!"
Nowadays, just about everyone just types one space after a period at the end of a sentence, so if you find yourself chatting to a
red-headed green-eyed coed on-line who double spaces after their full stops, don't be thinking you are so lucky.
