Seems like you had it a little more strict than I did at Straight.. however we did need to only sing songs that we sang in group at the host homes or whatnot.
I remember one time I became rebellious, if we came early to the building, we were sent in a room and had to sit on the floor indian style, I refused to do that and I was talking to another 1st phaser, we started singing Ozzy songs and Rush songs to piss people off.
Needless to say I ended up in group kicking a chair, I think I hit another 1st phaser with it, I don't remember, I felt horrible about that.
I was slammed to the ground and told to eat the carpetting. I was on very close watch for the next 2 weeks after that.
