tough n tire day

tis lantern model
we spent a lot of our times and effort on it
but at the end it's still failed

the main reason course of fail we still dunno
but
when i saw the failure happened
i directly feel very moody
at the same time i d feel wanna stop doing anything

my mind was full of disappoint
coz we really spent a lot of money, times n effort on it
we started doing model early in the morning for everyday
then went home after 12am
seriously it's a tough and tire period

think certain ppl feel wanna continue to do the experiment
but try to think for other ppl's situation
our neightbour need to sleep as well
but if we keep burning the things n come out the haste as well as making noise during such late time
it will annoying other ppl rite
somemore..all of us seriously tiring
should we take a rest n do it tmr?
