Good morning. I'm Rachel Martin. There are really two kinds of people in the world, those who type two spaces between sentences and those who just use one.

But if you cannot stop yourself from typing two spaces, not to worry. Throw caution to the wind and ask Word to just ignore the grammar suggestion. Transcript provided by NPR, Copyright NPR.
