I think one of the key things to remember about human beings is their optimism and their faith. For example, in America, you have a country filled from sea to shining sea with people in the food service industries all of them convinced that a person can somehow make a drinkable cup of tea using only a) a teabag and b) a cup and c) a container holding water that was once reasonably hot. They bring me these three ingredients proudly, convinced that somehow I'll be able to combine them in a way that will produce a drinkable cup of tea.

And in a credit to my own optimism and faith, I keep trying. Haven't succeeded yet, of course. But still. It makes you proud to be human.
