Digital communication strips away the human voice, leaving punctuation, capitalization, and phrasing to carry our intentions. The acronym "LMK" is neither entirely toxic nor universally harmless. It is a linguistic shortcut that demands mindful usage.
Taking an extra four seconds to spell out "let me know" changes the emotional temperature of an exchange. Adding a timeline removes guesswork for colleagues. Padding a casual message with friendly context reassures friends and romantic interests. Clarity and intentionality remain the best defense against misunderstood screens.
