I had to visit a well known playwrite, now deceased, but then retired. I always wear sandals in summer if I can, and turned up in my sandals, and he apparently told his friends that he was very unsure of any professional wearing sandals "for god's sake". I dont like the ideas of going barefoot to attend the sick, especially as I was once subjected to a display of toe picking on a ward round by a casual doctor friend, and it made me feel awkward, let alone what it did to the patients, I wear socks with long trousers, and go barefoot in shorts, depending on whether I'm working or off duty. What on earth am I discussing this for???? Got to go -- better things to do.
