Over my 60+ years in the WT I've occasionally seen kind brothers and sisters help others out - but it's been rare. My husband I have helped brothers and sisters when we were able. But in my experience never, ever have the WT organisation stepped up and it's not often a witness will help, either. They will help their 'friends' in the congregation.
When my husband was sick and couldn't work and we had literally nothing coming in, all I ever got from people in my congregation was 'I'll pray for you' and then to rub salt into the wound I was counselled by the COBE for not having enough money to attend the convention!
