1. It’s one space after a period, NOT two.
I sympathize. I used to do this too, but putting two spaces after each sentence is an antiquated rule. It’s time to stop.
Wide spacing after a sentence was a fashion with traditional typesetters (think Gutenberg). The rule to hit space twice after each sentence was developed in the early 20th century when typists tried to follow this fashion on their typewriters.
Excellent tips to keep in mind.
