Mail server isn't down.
Colleague just walked into my office on a Monday morning and did the thing: "Hey, any idea where we ended up, do you know?"
First she's said to me since the end of the day Friday. No context, no reference, nothing. I responded, intentionally like an asshole, with a blank stare and 10 seconds of silence before she got the idea that it would be wise to let me know what the fuck she was talking about before expecting an answer.
