Maw he sounds like an entertaining little chap!
Yes, I think we need to live and let live. Two incidents: the only time I have ever complained about behaviour was when a group of football supporters got on at Wembley and started to sing “you’re going home in a f*** ambulance” and talk very loudly, with a lot of swearing, about the opposition. The second was when a young man was listening to music on his earphones and the sound was leaking. A lot of us in the carriage, me included I’m ashamed to say, rolled our eyes and tutted, but one man got up and asked him to turn the music down. The music playing young man apologised to the whole carriage and said he hadn’t realised we could hear. So, by all means complain when someone is being deliberately antisocial, but give people the benefit of the doubt.
