I came close to saying "I'll be back in a bit," and then going for a pint... And then realised that I'd have time for more than one. And then... well, I just fast forwarded the tape. I remembered there was a meeting that night, so I checked where it was with my phone, made my excuses and left. At least in the meeting people would be genuinely glad to see me, and honesty is appreciated.
Great job, Emily!!!!!
