At one point, Tim left to go to the bathroom. I didn't feel awkward at all sitting there by myself until my coworkers walked up. Then I said, "Oh hey...I'm not sitting here by myself." And suddenly I felt very awkward. Then one of my coworkers patted me on the back and said, "Oh it's ok, honey."
When Tim got back from the bathroom and I told him about it, he said, "Why did you say anything at all about it?" Nobody knows, friends.
