My word processor does not believe in contracting “it is”. My phone does not believe that “it” can ever take a possessive. I assume this is a manifestation of some kind of battle between Microsoft and Google, but it would be nice if they’d loosen up and take less absolutist stances, vis-a-vis autocorrect. Oh, and MS Word? “And then” is worse than “and” or “then” 99.99% of the time. Cut it out.
