i was in 4. 1st - i was young and had lots of friends. but kids were dropping out left and right. and stupid issues.
2nd - almost everyone in the hall was related and it was really annoying. pioneers were mean, a lot of gossipy women. pioneered right out of high school in that cong.
3rd - very cliquish (sp?). u were either cool or u weren't. somehow my husband and i were "cool" so we were in. it was his cong. when he and his best friend (who wasn't cool) pioneered, my husband who petered out after like the first 2 months was always very encouraged and even though he missed his hours by a long shot he still got to go to pioneer school. his friend who worked his arse off and might have been slightly down on his hours one or 2 months was constantly berated. even though i was in the "in crowd" i couldn't stand it and hated to hear the things the "cool" elders would say about the "uncool" people in the cong. i felt so bad for them.
4th - very, very nice cong. nice, down to earth people. sweet. caring. i felt so bad leaving them like i did. one day i was their best friend and the next day i was gone. (by the way, cong. #3 warned me about cong #4 saying that they were all old, boring, uncool...)
