Not an exclamation point, not a question mark, not an ellipsis… a simple period.
We’ve exchanged ideas and statements for impact when they used to be about everything before the punctuation.
Want to impress your Team Lead with how to fix that Nuclear customer’s problem?
Send your answer and end it with a period. When you end it with a period, it’s a signal that it will be resolved, it will be fixed, you will get it done and the customer will be happy.
It’s not a hopeful question mark or an exasperated exclamation – it’s what you said it was going to be, nothing more.
