WT and JWs almost never get engaged in charity work. I say almost. In 1989 the only charity work we did when Romania was in the mist of revolution and there was a call for helping other JWs so they not starve as the political situation was extremely difficult. We purchased a lot of flours, cooking oil, sugar, and other bulk items that were snet to Romania. That was the ONLY time I seen any charity. In 1997 and 2002 Czech Republic was devastated by widespread flooding. I know JWs who were totally flooded out and lost everything, yet nobody from HQ in Prague offered any help. While some individuals did help the other by donating some crap, there were JWs who lived in homeless shelter until flood water receded. The only help came from the government. Yeah, you are flooded, but only advice you got was doing more field work as did one crazy now deceased sister.
My life after WT, I had engaged in various charities and seen so many others around me to do so. My father-in-law did AIDS ride. We did breast cancer walks as we have lost women friends to it, organized food banks at work, etc. Charity work is a distraction from a field service.
