That was weird and unpleasant. For several hours I was painfully aware of all the stale carbon dioxide everyone was expelling into the air around me, how bad their microwave popcorn stank, and worse, how much fucking talking I have to do just to negotiate the office hallway to get to the bathroom. But I feel much better now, and no longer wish to avoid human contact.
So: Hi! How's it going? You look really nice today.
