No, they decided to play computer games together. And to raid the school snack shop.
That was Saturday, and the boys apparently played computer games all night long at Phuket's Cherng Talay School.
Come Sunday at 11.30am one of the teachers who lives in accommodation at the school investigated the computer classroom . . . and caught the boys at their games.
The room was a bit smokey from the cigarettes and further investigation revealed the boys had broken into school shops for noodles and sweets.
The dressing down the teacher gave the boys had no effect, so the first teacher called in a second, and a third and a fourth.
The boys still showed not the slightest sign of saying sorry, not a hint of being contrite. So the teachers, by then numbering five, called in the police.
Yes, they told the officer, they hadbroken into the school room using a small knife. Yes, they had raided the snack shop. Yes, they just did it for fun.
Were they A students? Not exactly, but they were smart enough to use candles all night. Switching on the room light would have led to their discovery.
The police officer made them clean their mess, took them to Cherng Talay station, and made them call their parents to come to pick them up.
But with the three boys aged just 11, that was all the law allowed him to do.
