Why do you want to do what you do? the Intentionality of snacktime

"It's time for a an orange" I said.
"Why's it time fo' an orange?" said Anton.
"because I assert that I want an orange."
"Why do you want an orange?"
A good question. I had just stirred the soup and hadn't been thinking about oranges. But there were a small basket of clementines. Why did I want one?

Where did my intention come from?
