Finally called Mum and Dad in London. All OK. Walked to San Petro XXXX at the Vatican City. Refused entry because of our shorts even though we had taken t-shirts with us. Staggered back in the heat. Collected our film then met Marina and co. in Piazza Navona. Spent the day with them sightseeing and shopping. Saw Villa de Medici and gardens. Bought another top. Very hot. Lots of walking in the sun. At least 37 – 40 deg C yesterday. Mark got burnt. Saw a big gay and lesbian parade going through the street outside.
