Let's say there's a guy named Joe. This Joe works at this place that sorta runs non-stop until the work day is done. While Joe is working away at his job, which as noted is non-stop, Joe frequently comes into something resembling contact with persons who work somewhere else. There is overlap between Joe and his colleagues and those working at the other place whose job also requires interaction with Joe and his group. Let's say Joe finds a particular employee at this other place, who he notices while on the job, kinda stimulating. In a normal situation with a normal person, one would go over and initiate conversation. However, even if that was the case - ie, Joe had no qualms about initiating any conversation - while in contact with these other persons Joe is not at liberty to take time away from his work to mingle with other persons, at this particular environment more than any other time. To some extent, and perhaps it is a bit of a stretch (but only just), to take time away could be a matter of life adn death or milder, disaster. So what is Joe supposed to do if he desires stimulating conversation with this other intriguing person, who admittedly he knows nothing about? Truly an somewhat difficult situation? Any suggestions for this Joe?
