I had to due to the trouble my son got into. I went last Sat. and the Sat. before. Each were 4 hours long. They did have some great ideas, but I almost wanted to tell them (I still might on the feedback sheet I fill out) o.k. that all sounds great but we live in a real world here. You know the calm replies we are always suppose to have with our children. The patience of a saint. Things like that. It's all good in theory! I don't like talking in front of or to strangers and of course we had to. It was o.k. and I admire the moderators/facilitators that take there time to do it. Honestly the only reason I signed up was to get out of paying 30 bucks a month for 6 months while my son is on probation. Some of the others in the room - most of them - that were far more talkative during the class probably got more out of it then I did.
