In this instant age, we think we don’t have time to proofread. Or, we say, “That’s why they created spell check.” But sending e-mails and documents with typographical errors and poor grammar says that you don’t care. You don’t care enough to re-read what you’ve written, or run spell check, or double check how to spell someone’s name. And if you don’t care about your interpersonal communication, you’re saying you don’t care about the person with whom you’re communicating. It’s personal.
