How to Choose the Right Alternative

  1. Read the alternative out loud before sending. If it sounds like something you would actually say, it is ready.
  2. Save two or three favorites instead of memorizing the whole list. Rotating a few keeps your wording fresh.
  3. Avoid sarcastic or funny alternatives in serious conversations. Tone misfires are hard to unsend.
  4. Match the register to the reader: professional for work, casual for friends, flirty only where it is clearly welcome.
  5. For texts, shorter is almost always better. Trim any alternative that takes more than one breath to say.
