I started school at 5 and the trip to school involved a short walk across the park. Then the school moved to the other side of town, involving two buses. In those days my parents didn't have a car - not many people did, and an older girl who went to the same school was asked to take me with her. However, she proved to be completely useless and kept leaving me behind. So I just got on with it! Before I was six, I was catching the buses by myself with a change in the town centre and doing it twice a day, because I went home for lunch, having absolutely rejected school dinners! (I had 20 minutes in the house, before I had to go back to school!)
I survived!
Of course , times were a bit different then, but I still feel amazed that I was allowed to do it!
Incidentally, one day, when I was about 8 or 9, we had a new teacher, who kept the class behind at lunch time to finish some work. I told her several times that I had to leave to catch my bus or I wouldn't have time to get home, but she ignored me, so I nipped out of the window (ground-floor, low windows!) and ran to catch my bus. By the time I got home I was so upset and in floods of tears that my parents kept me home for the afternoon and rang the school. I was terrified to go to school the next day, but the headmistress was obviously sympathetic with the circumstances and just told me never to do it again
