I think this is a good observation, and a good post.

the first bit about wasting food/ drink I can really relate too...

the other day, for example, I had to throw out a bottle of doctor pepper because the liquid had gone flat.

my first thought wasn't.. well, that's a good thing done, my first thought was.... oh, what a waste of a drink- now no one's going to drink it and I'll be cursed if I buy another doctor pepper for wasting that one (it really affected me and made me feel so depressed)

you know I don't know why it is

maybe it's because of people in africa who have nothing.. here I am with a doctor pepper (it's flat, but it's a doctor pepper), and their's people in africa that don't even get a chance to have that.
I don't know why I believe I'll be cursed. maybe It's the same sort of thing
