Sing Something Simple - aaaaaagh! I hated it, it depresses me even as a child and was indicative of school next day. Looking back, though, my schooldays weren’t bad, but I probably thought they were at the time. I was the shyest child ever and I found team sports, reading out loud, having to express myself etc absolutely excruciating. We watched Sunday Night at the London Palladium when I was an older child and I remember not enjoying it much - probably thinking of school next day! I still get that Sunday evening feeling sometimes. I think it’s habit formed from 60 years of Monday mornings (school then work). When I remember that I don’t have to get up early for school/work next day, I feel better. I’ve been retired just over 2 years. Some of my working years were better than others, depending where I was working who I was working with, but mostly they were quite good, in hindsight.
