Some interesting comments...
Being an elder was no picnic, but one good thing I took away was an appreciation for strict confidentiality (though confidentiality was often disregarded by other elders, and I was dismayed to learn how often things ended up becoming publicly known). The upside of this is that now I have several friends who know they can trust me, and as a result, will talk to me about some matters close to their hearts.
Now don't get me wrong - anyone can learn to keep things confidential. Being a jw elder does not necessarily mean that I wouldn't have been a good confidante anyway. But after hearing some pretty crazy stuff and keeping it to myself to this day, it reinforced the inclination I already had to keep things private on behalf of others.
