from Eros Atalia's book
how to kill yourself no.3 "eat watusi" (watusi is a fire cracker, highly poisonous)
the flower is an offering for one' self before commiting suicide. i just thought maybe after killing yourself people will mock you and say you're stupid and not give you flowers anymore on your funeral. Im still a little bit sentimental... hehehe
note: kids dont try this at home... it's very dangerous.
