Grammar Police Mom
People who are fussy about grammar can get on your nerves quite quickly. They are proud to point out your faults and make you feel embarrassed.
All in all, they’re going to annoy the hell out of you, but if it wasn’t for them or your grammar police mom, you would continue to make this error, and you wouldn’t even bother fixing it. If in this conversation your mom is a lot like your mom, thank her right away and send her some fail grammar memes in her way.
