NO dancing.....young people might rub together and end up *petting* which might lead to *heavy petting* which could lead to fornication
NO drinking....could lead to public drunkeness. One young brother had 4 beers where beer was allowed and he was DF for it. He was *Publically Drunk* and therefore a bad influence on the rest of us. All he did was giggle the whole time. No loudness, no rowdyness, no barfing....just giggling. That was a bad influence.
NO music....at a *house party* they played the Beach Boys Greatest Hits over and over for 4 hours....My mother would not come and pick me up. I called crying and begged her to come get me...I hated the Beach Boys....I wanted to hear AC/DC and Van Halen. They kept playing the same LP over and over and over.
No I cannot think of anything good. It really was all bad. From going to meetings to going out in service. Our cong was made up of a bunch of tight ass elders and their tight ass wives and kids.
