Is the flower pot half empty or half full?

I took this photo in Luxembourg city, Luxembourg in January 2014. There were several flower pots on the street and the photo shows one of them. It was in winter, so the flower pots looked like this, and I thought it was cute. There was a bus stop near there, and some people who was on a bus or who was waiting a bus did a double take like how come an Asian woman take a photo of an almost empty flower pot. There's a common expression 'Is the glass half empty or half full?' Come to think about it, the flower pot was half full.
