So, there was this package...

Me: Awkward, I saw this in your mailbox, thought I'd bring it to you.
Awkward Coworker: What is it?
Me: I don't know. Open it, I want to see!
Awkward Coworker: Oh wow, it's uh. Brackets?
Me: Did you order those?
Awkward Coworker: No...brackets and a bracket catalogue! Score!
Me: Your last name is [Jones], right?
Awkward Coworker: No...it's [Smith]. Oh, this package is for...someone else...
Me: ...oh my god. I knew that. I know your last name. What the hell is wrong with me?
Awkward Coworker: *endless loling*
