Today the MOtheeirS who knows how to work their camera wasn't there so I could't get the autofocus to work. I gave it to Alex and said "Help", he made puzzled sounds then pressed "Reset" which seemed to workBut FWIW I had a pee before we went, was there for 2 hours without a pee and didn't need to go straight into the loo when we got back. Gosh, the days of peeing every 15 minutes are long gone, phew
