76: On a train at night

I was on a train late at night when at university - the guard making his way through the carriage was black. There weren't many people in the carriage - and one man was obviously drunk. He started shouting at the guard and it soon deteriorated into racist abuse. He was very aggressive - I felt really angry and that I should say something but was scared to say anything so kept quiet. The guard ignored the abuse with a tired expression his face, like it wasn't anything new. I felt really sad and that I should have been braver and spoken up.
