How to Choose the Right Alternative

Adjust one word to make it yours: swap a name, a detail, or a reference only the two of you share.
Avoid sarcastic or funny alternatives in serious conversations. Tone misfires are hard to unsend.
Match the register to the reader: professional for work, casual for friends, flirty only where it is clearly welcome.
Do not stack two formal phrases back to back. One polished line plus plain language reads better.
Read the alternative out loud before sending. If it sounds like something you would actually say, it is ready.
