Evening walk

Finally starting to feel a little better. Went into work in the morning to see the students but left just before 2 pm to drive to pats to meet up up with my very good colleague Alan and his wife finally visiting from Melbourne after the covid pandemic. Peter and his wife where there too, it was a very jovial afternoon, Dallal had cooked some lovely food. Drove home and worked puzzling over this pH problem in the mixed solvents not sure yet what to do about it, finally dragged myself away from my desk at 8:30 to go for a lovely evening walk as the air cooled and the sun set.
