I knew a young brother who was known in the congregation for his laughing very loudly for very small things,we would wonder if he was quite all right but when asked how he was doing he would reply that everything was OK. Was talking about pioneering, etc. In fact he was living in an unfathomable solitude, had few, if any, friends, as he was a bit limited. One day we heard that he had jumped under the wheels of the subway, he was in his early 30s. He was buried very discreetly, almost on the sly, JWs don't like it to be made public that some of them didn't believe they were the happiest people in the world. So sad, makes one ask oneself, after, if we could have done more for that person.
