I hated having to cut off my "wordly family". I lost so much time out on Service, Meetings, and all the older general BS. I could have spend that time with my family instead.
Also, i hated how "fake" the people were.
Lastly, the guilt they place on people for not going to meetings or service. If i missed a meeting my phone would be ringing asking why i was not at meeting. I erally hated that.
