"one school pen"

Jetted off on a canoe tour of the lush backwaters of Alleppey, Kerala. The day started, in food terms, with idiyappam, cooked by our canoe guide's wife. It's a noodley rice mix sweetened up with coconut. Delish, (as are most foods!) although this one seems to be one for the home life. We ate in the guide's cute, modest home that overlooked rice paddies in one direction and a small canal on t'other. The guide, a man in his 50s, referred to me as his "daughter" as I am in fact the same age as one of his daughters and then a tattooed Danish girl in our group as his "sister" even though she's only five years older than me! Slightly offensive. Anywho, we took turns to paddle through the tiny canals of the backwaters whilst our guide had convos with his fellow villagers as we slowly drifted past at a leisurely rate. We were nearing the end of our idyllic, peaceful tour when a troupe of primary school kids passed us on the canal pathway. They started shouting the usual "one school pen!!" at us, and luck was with them that day, as the Dutch couple on the canoe had a big stash with them ready for just this moment. Pandemonium ensued as Mo hurled school pens from the boat to the kids on dry land. Some were being a bit cheeky and trying to nab themselves two. And then one over-enthusiastic little boy overstretched and ended up in the water up to his waist!! Mega lols!!
