Socializing with the crew is not necessarily a two way street. It's great when crew members join passengers at various social functions but be assured the crew go out of their way to avoid passenger contact when off duty and on shore leave. They want and need the time to be with their own. When approaching a crewmember off duty, even to say hello, you are cutting into his/her personal time. We avoid all such personal contact as this point has been clearly and understandably made.
