How to Choose the Right Alternative

For texts, shorter is almost always better. Trim any alternative that takes more than one breath to say.
Do not stack two formal phrases back to back. One polished line plus plain language reads better.
Avoid sarcastic or funny alternatives in serious conversations. Tone misfires are hard to unsend.
Adjust one word to make it yours: swap a name, a detail, or a reference only the two of you share.
In emails, pair a formal opening alternative with a warm closing one to sound polished but human.
