Here's a pet peeve of mine: Clients who answer "It's been a minute" when asked when some event occurred. What the hell does that mean? Where did this usage come from? I think I've only heard this in the last year or two. Is this usage national?
Unfortunately, lawyers usually need to know when things happened! We get annoyed when given answers like this. My instinct as a lawyer is that if my client seems evasive when answering a question, I've just hit upon a key problem. Of course, "It's been a minute" isn't necessarily evasive but it sounds that way even when it isn't.
