Talking to a 10 yr old kid

Very challenging to talk to a 10 yr old kid, esp when i seldom mix with kids cos i am the youngest at home. Heres a msn conversation i had at work today with my fren's brother...

boy: I hate my mum
me : why?
boy: cos she promised to buy me a hp, but then now say cannot
me : do you ask her for the reasons?
boy: no, i hate her!!!!
me : what happened to your old hp? Spoilt?
boy: my old hp cannot type chinese, i need to type chinese
me : why?
boy: to my chinese teacher who is in china now, she cant read english
me : ok... (trying not to oppose the kid, so that the communication wud not be strained)

boy: see.. i need the hp, i duno why my mum dun want to buy.
me : a new hp is very expensive, mabbe thats why your mum feel its not worth to buy
boy: no.. i am aiming the xxx model, only $299!!!
me: *gasp* (v hard to talk to kids)
boy: she said only if the hp is spoilt, then i can buy... mabbe i will purposely go and spoil it.
me: Perhaps its more meaningful to play ur part to help your family save money, isnt it better?
boy: aww.....

boy: haha, now i am left with a 1 more battery, if this battery spoilt, then i can buy a new hp already, yeah!
me: *damm* (did he really go and spoil the hp batt?)
me: I only have my first new hp when i was in NUS yr2, i always use my dad's and bro's old hps, my mother also use a very old hp, even my managers now in HP also use v old models like 8250.
boy: but all my frens use 7610i, they so rich, so good, i so poor....
me: you shld work towards being cleverer than them, smarter than them, having better results than them, and not having better hp than them (i kinda regretted preaching too much at this stage).

***after lunch time***
boy: Hi, i decided not to buy the hp already
me: oh why?
boy: cos my parents explained to me already, when the old hp is still working, i shld not throw away cos thats waste of money. Its also part of buddhism teaching, be contented and use what is needed.
me: well done, your ability to absorb and apply the teachings is far more better than owning a new hp...
boy: thanks!
