Me (explaining about mirrors – why we see a reflection in the mirror, how they reflect light etc.): So when there’s a light source, it’ll be reflected by the mirror etc etc
Student: So how do our eyes see things? There’s light coming out from our eyes?
Me: You think you Cyclops ar?

The same student as above, the one that farts a lot and thinks eskimos are animals and celebrities are manmade, comes back from getting a piece of tissue paper and starts digging furiously in the orifice that most children his age are fascinated with – the nostrils. He ransacks his nostrils for a while with the tissue that he twists into a thin strip (a nifty improvisation that almost all children are fond of), pulls out the tissue paper, looks at the efforts of his labour and stuffs another clean part of the tissue into his nose again with a satisfied expression, continuing his excavation project. Then he asks me, with a half-stuffed nose:

How come sometimes I dig my nose, then got some red red stuff on it (the tissue)?

Me: Blood lor. Who ask you dig your nose so hard. Our nose got tiny blood vessels and if you dig too hard you might scratch them and there might be blood.

Student: Usually it happens when I dig my nose when it’s very dry.

Me: er..then wet your nose/finger firs..WAIT WHY AM I DISCUSSING NOSE-DIGGING STRATEGIES WITH YOU
