The late evening when I get to snuggle my wife and watch TV after the kids have gone to bed.
Noon, when the sun is high.
It changes. In the summer I would say the mornings. All the sunshine is beautiful, sitting on the deck with my coffee is relaxing, listening to the birds, etc. But in the winter I would have to say bed time... Snuggling under the down comforter, reading a book with a cup of tea.
