Meant to add that if he left, and we did call each other, we would kind of have to admit that we're not just talking because of work, KWIM? I mean, we know that now, but we can use the excuse that we work together, so we have to talk. It may not seem like it, but we really have never crossed a line. Never said anything inappropriate or even remotely suggestive. If it's the last day before a weekend or holiday, and we haven't talked for whatever reason (not unusual when we're busy), one of us will always shoot an IM to the other telling them to have a good weekend or a wonderful vacation or whatever. I'll always tell him to take time to relax, since he works all the time. He'll sometimes respond with a heart reaction. No one ever uses that heart reaction at work 'cause it is kind of weird/personal. But he'll use it when I send a personal note to him.
