It’s not that difficult!

Grammar Cop has been on hiatus, but now she’s back and on a familiar rant. Apostrophes! Stop using apostrophes incorrectly. It isn’t that difficult. 

Do NOT use apostrophes for pronoun possessives: hers, his, yours, ours, theirs, its. 

Do NOT use apostrophes (except in cases of acronyms) for plural: ATMs or ATM’s 

It’s is a contraction of it and is. Its is the possessive of it. It’s not that difficult!

Rant over.
