Kill me pls...

Been working with this colleague of mine for the past 3 weeks. Those whom i have chatted on msn would know that i am complaining abt him asking stupid qns...but then i can never predict that under all these stupid qns...his basic accounting knowledge is also a big question mark. Note here that i said basic accounting knowledge. Simple double entries could be extremely confusing for him!! Tell him he is wrong and he still dare to argue with me...another 2 more days and i am done with him. Pls pray i dun loose my temper...
