I always felt like I wasn't good enough, and was shocked to realize a lot of JWs feel that way...even elders! Why does everyone feel so bad? Wasn't Jesus message to be refreshing?
I also didn't like bothering people on service - waking them up, interrupting their breakfast, or wandering into their backyard because they were gardening. I would be scared if people came into my backyard when I was doing yardwork!
Also, I wouldn't listen to a Mormon because I felt I had the "truth," so why would I expect them to listen to me when they obviously think they have "the truth?" They probably feel God drew them to their religion, so who am I to say they are wrong?
