The weather is mixed today, but I can still see office workers sitting in the courtyard to catch any bit of available sunshine on their lunch hour.

I rarely, if ever, sit in the sun these days. I developed a skin condition called vitiligo many years ago. I have patches with no pigment on many parts of my body. Being fair-skinned and freckled it’s not so bad, because if I stay very, very pale I can get away with it, even if lots of my childhood freckles have simply disappeared. Dark skinned and sallow skinned people are not so lucky.
