“If I can’t clearly understand a person’s first sentence due to poor grammar, spelling, or punctuation, I don’t bother deciphering the rest.”
For me, it’s “your” vs. “you’re”. My grammer and spelling are nothing to be proud of, but people sound stupid to me when using those words incorrectly.
And don’t get me started on “there”, “their’ and “they’re”.
I hate “loose” instead of “lose” and “discrete” instead of “discreet”. Ack.
I receive a piece Spam every other day titled “Your Approved”. even if it is a legit business, who do they think they’d attract? (Or perhaps it is intentional?)
