I recall many years ago going to Wimbledon straight from work to meet my flat mates. Having stayed to the bitter end, there were hoards of crowds waiting for public transport, so we decided to walk “across country”. Shortly into this journey, and for no apparent reason, the heel came off my shoe. We had no idea where we were and could not see any signs of public transport. I tried to rip the heel off the other shoe, but it wouldn’t budge, the only option was to limp the rest of to way, the barefoot option being the alternative. I think we arrived back way after midnight!
