I'll be first to admit I experience no shame in substituting a trio of hearts, flamenco dancer, or exclamation point for a sentence wherever appropriate. Texting and online dating have made acronyms and emojis staples of conversation -- and sometimes, nothing is as articulate as a smiling pile of dogshit.
But even if stand-alone images and punctuation marks are high-functioning replacements for complete sentences, there are still those those fleeting moments when we choose to use actual words, strung together all in a row, to communicate. And in those cases, GRAMMAR STILL MATTERS.
I'm not saying it's unforgivable to have an occasional autocorrect blooper or typo, aka act like a human being. BUT! Your text messages shouldn't read like accidental texts sent by my 5-year-old niece. If you split an infinitive, so be it -- but using the wrong form of "there" really has that special je ne sais quoi guaranteed to kill my lady boner. Here's why.
It seems lazy, and lazy is unattractive
Not that you have to pull out the thesaurus and make perfect selections for a seven-word text, but it won't kill you to just re-read what you're about to send. Intelligence is kind of hot and appearing as such makes you seem capable of coherent, rational thought. Also, this kind of proofreading will allow you to fake sobriety far deeper into an evening than your unedited texts would belie.
