Meanwhile.....I got teacher who threw student's stainless steel water bottle down from third floor just because the student drank from it when the teaching was teaching. Bottle ended up hitting principle head who patrolling below. (Sampai berdarah) 

The principle (bloodied) came up to third floor and entered each classes asking who threw the bottle down....until our class....wakakaka, straight away all students pointed to the teacher. 

That teacher got called into office for that day and got scolded hard by the principle.
Our homeroom teacher asked us what happened in our class and told us that 'bilik guru' kecoh dengan bunyi guru besar marah maki-hamun

The teacher bought new stainless steel water bottle to compensate the student next day. That it.
