Unexpectedly quite difficult

When I was in Greece, I was interested in everything in Greece even mailboxes, phone booths, flags and such. Then, I took a lot of low-key pictures as well. This is one of them. Juxtapositional the flag of Europe and the flag of Greece. The blue sky and the white cloud create a beautiful contrast with flags. I love it. However, I realized that taking a picture of flags is too difficult. It depends strongly on wind. I needed to wait for the wind, but sometimes it was too strong. Anyway, this is the most photogenic one. Phew.
