I must confess that I only did it once. I also killed a blackbird with a capapult in the elms growing along the railway embankment there. I only did that once as well.
Alas, although keen, I was not good enough to be picked to play football for the many teams playing locally. I did managed to get 'sent-off' while watching my friend play for the Boys Club team on Cuckoo Schools playing field.
I was behind the goal when two chaps from the visiting team lifted up the goalposts about a foot, then left me alone behind the goal. When this was brought to the refferee's attention, he assumed that I was responsible and ordered me off!
