How to Choose the Right Alternative

Match the register to the reader: professional for work, casual for friends, flirty only where it is clearly welcome.
Adjust one word to make it yours: swap a name, a detail, or a reference only the two of you share.
Save two or three favorites instead of memorizing the whole list. Rotating a few keeps your wording fresh.
For texts, shorter is almost always better. Trim any alternative that takes more than one breath to say.
In emails, pair a formal opening alternative with a warm closing one to sound polished but human.
