why?

i have put together my presentation, and am ready to deliver tomorrow.
yay.
there is one point that I hope someone will ask me about
why is my project called 'the casuarina tree'?
if nobody asks me then they will have not thought enough, I think.
but i am one step ahead...
if...one brave audience member asks the question...
I am going to give them maybe an answer, but a print of the casuarina tree!
yay.
if only my peers read this blog!!
haha.
