Once, when I was 15 for keeping a huge pack of firecrackers (which are ilegal back home) for another 'brother'. I wasn't baptized then, but they took away the microphone handling 'priveleges'. The day after that, I left on vacation, when I came back to weeks later, the brother I was holding the fireworks for spoke on my behalf and my 'priveleges' had been restored...
Years later I had to go again because my roomates (we lived at an apartment inside the Kingdom Hall complex), specially one of them, had raised false accusations against me while I was out on holiday for a weekend with my family. All because they weren't doign their assigned chores around the complex and some elders noticed and call them on it. They thought I had ratted them out. During my abscence that weekend, the elders passed judgement in my abscence and decided to kick me out of the apartment and almost stripped me of being a regular pioneer...
It worked out for the better. I was pioneering and going to school, I didn't work, so one of the arrangements was that the other 2, who worked, would shop for groceries and I would prepare the meals. They never did, they would eat out ever so somedays I would hardly have anything to eat, or would have to wait for my mother to come to the meetings and she would bring me some food. Better yet, the living room furniture, 2 of the beds, the stereo, TV and VCR in the apartment were mine, so when I left, I took it all with me.
