This is probably something women in the organisation experience more than men. Even though we were instructed from the platform to use our youth to go pioneering, the older sisters in the congregation always seemed to be pushing younger women to marry and have children so they would be 'happy' like them . I guess this is mostly the only joy you can have as a JW woman (Especially for keeping you entertained during otherwise boring meetings).
When I got married (far too young, lucky it worked out) there was instant teasing, encouragement, etc to procreate. This despite the fact I was barely an adult myself. I know this happens in the real world as well but it seems to be particularly bad among JWs. They were particularly upset that I continued my university studies, and I was always greeted with such remarks as 'you do too much' (i.e. you do too much of what we don't want you to do). I actually felt very isolated because all the 'sisters' around me didn't seem to care about developing themselves as a person, so they would have something to pass on, but were more intent on having children, so they could have children, and so on. I would love to have a child one day, but I want to know who I am first (at least a bit more than now). I always felt like I had to make excuses for this decision. Luckily I stuck to it and have my degree and a real job Still hurts that all my efforts were valueless in their eyes.
