A friend often sends screenshots of previous text conversations we’ve had to prove I’m wrong about something. It makes me feel as if we’re in a business relationship. Is there a rule about this? —Anonymous, New York

The rule you are searching for is: Nobody likes a smarty-pants. Save screenshots for serious misunderstandings, not every little inconsistency. Text your pal: “It makes me feel bad when you send screenshots to prove you’re right. Please don’t.” Then send her a screenshot if she disregards your request.
