It was the same at our school, until the deputy head force fed me tapioca and kept clamping my mouth shut until I swallowed each spoonful.
She seemed well satisfied with her efforts for a few seconds until I projectile vomited over her, and the girl sitting next to me.
I escaped the cane, but the 'news' spread round the village like wildfire. My mother was not amused, marched to the school and gave the teachers within earshot both barrels (or so she told me). From that point on I was excused tapioca, and have never had it since.
