How to Choose the Right Alternative

  1. For texts, shorter is almost always better. Trim any alternative that takes more than one breath to say.
  2. Save two or three favorites instead of memorizing the whole list. Rotating a few keeps your wording fresh.
  3. Read the alternative out loud before sending. If it sounds like something you would actually say, it is ready.
  4. Do not stack two formal phrases back to back. One polished line plus plain language reads better.
  5. Adjust one word to make it yours: swap a name, a detail, or a reference only the two of you share.
