It's only to be expected that JW's are somewhat socially hobbled, especially born in's. As a JW, you are required to select your friends and marriage mate from whatever pool of JW's you happened to be associated with. You already know what everyone around you beleives or thinks about on almost every issue or topic. You know what they will or won't do in any given situation. You know what activities they have during most of the week. You know they don't have any political ideologies or aspirations or major educational goals. They are all taught that in order to be sheeplike and agreeable, they must defer to someone else. Basically you only have to find someone you click with personality wise and the rest takes care of itself in a way. You don't get a chance to develop any strong interpersonal skills for use when getting to know someone who isn't a carbon copy of yourself. On top of that you generally are well practiced at keeping your real thoughts and desires (if you even know what they are) in check and aren't comfortable letting others see them. As a JW, when you are around non JW's in an unavoidable social setting such as work or school, you have to keep a certain part of your life on the down-low much of the time. You can't openly admit, for instance, that most of your life's activities are based on the belief that the everyone around you is going to be destroyed by God soon because they (according to your beliefs) are part of Satan's world, no matter how good they may be.
It's tough to learn all the necessary social skills all at once when you find yourself outside the JW circle, rather than over a lifetime as most people in the world have a chance to do.
