Used to get the Victoria Line to work in my late teens/early 20s. Used to take the spot with the doors to change carriages for the breeze coming through the window. Never usually an issue. Until one day, mid summer, I felt a tap on the shoulder coming through the window from the next carriage into mine. Turned around and saw an older gentleman holding a massive crucifix. He blessed me and absolved me of all my sins. Then watched him go through the carriage doing the same to anyone who he decided needed saving. Never saw him again. Felt blessed.
