How to Choose the Right Alternative

  1. Adjust one word to make it yours: swap a name, a detail, or a reference only the two of you share.
  2. Do not stack two formal phrases back to back. One polished line plus plain language reads better.
  3. Read the alternative out loud before sending. If it sounds like something you would actually say, it is ready.
  4. For texts, shorter is almost always better. Trim any alternative that takes more than one breath to say.
  5. Match the register to the reader: professional for work, casual for friends, flirty only where it is clearly welcome.
