((((((Googley))))) My mother is fond of throwing this out, and when she did that to me when we were struggling with my son's diagnosis, I flipped out at her and screamed "Don't you make me hate God!"
Alot of people think there is a perfect saying to fit everything, and that if you toss out enough of these peious phrases, then you have done your bit. They are ususally, like my mom, great at being able to tell you what that reason is as well.
I frankly did not, and do not, feel comforted by that statement. I feel that yes there may be a reason, but I am unlikely to understand it, so it's best to just leave the issue alone.
