I'm going to just come out and say it - I would rather eat live spiders than hold any semblance of a conversation with a co-worker. I don't care what you think your day is like, how many carbs a tomato has, or whether you think your daughter is sleeping with their physics professor.
Since moving to a new building a few months ago, they've consolidated three of our buildings into this one office and people are everywhere. At this point I discovered an elegantly simple solution - if I smile at people, without breaking stride, I don't even have to acknowledge them. I even get the occasional compliment from my boss for being friendly when all I've done is find the most efficient way of ignoring people.
Yesterday I encountered my first snag in this plan. I received an email suggesting I had volunteered for a food drive. Given that I had never spoken to the sender (frankly I didn't even recognize them), I don't know how that's possible, but they were confirming my time slot.
Luckily, I had a definitely-real-definitely-not-impromptu conference call at the same time, so I wormed out of it, but now I can't seem to shake that I may have inadvertently agreed to Lord knows what around the office and won't see it coming till it bites me in the proverbial.
