Sometimes it depends on blood sugar. I know of a doctor who claimed if you tell him what you ate today he can tell you what kind of mood you're in.
For myself, if I eat a lot of donuts in the morning I'm cranky in the afternoon. Never fails. Not sure why.
Because the donuts are all gone?
If Lynx eats all the donuts in the morning, I am cranky in the afternoon when I discover no donuts.
