DS (7) is supposed to do his homework, i.e. write his sight words a few times and the following conversation ensues:
DS: I know how to write the words, so I don't have to practice them
me: it's always good to practice even if you know how to spell it
DS: well then I need a rubber/eraser
me: how about you go and find one? [giving options of where to go look]
DS: I can't find one
me: [goes over to general junk depository table - admit it you have one too?
]
me: and what are those? - [pointing at collection of Smiggle eraser animals - approx 6-7 of them...]
DS: I don't used those as erasers/rubbers...
me: [goes over to wall and bashes head (own) against wall as more yealding than DS's logic...]
