My daughter was considered "spiritually weak" because she wanted to go to college and expressed no interest in being a pioneer. She was excluded from anything going on at the KH, and in mean ways. People would talk about events right in front of her that she was not invited to. We talked to the elders multiple times. Too bad, so sad. The pioneers only hang out all together because they are always in service together, so that just makes sense. Maybe if your daughter was out in service more??
She eventually came to see that she would never be accepted or good enough there, and she told us she didn't want to be a JW anymore. It was horrible to watch because my daughter is the sweetest and most outgoing girl, and was friendly to EVERYONE at the hall. Honestly she probably would have been a JW forever if she had been treated with one speck of kindness.
Even my husband who is "still in" was disgusted by the whole thing and doesn't blame our daughter one bit. The good news is she is in her second year of college and loving it, doing well, living a good life. She also held onto her values, no drugs, no partying...contrary to all JW expectations.
