So, deep down, these poor souls still think the meaning of life is to follow a carrot dangling before them. They are not thinkers. Apparently, they just can't bear the burdens JW's are called upon to bear. So they leave, then come back and load the burdens back on. Then the burdens become too heavy, and they leave again.
I agree that these non-thinking types need to do some homework and figure out that blind obedience to charlatans cannot lead to a better life in any way. It's harder for some than for others to think for themselves and forge their own path.
So sad!
