Yesterday, I was travelling in an Overground train in London and got chatting to someone who works as a plumber. Let’s call him Peter (not his name).

Peter the Plumber is maybe in his late twenties. I could be way out. He could be in his early thirties but, if I had to guess, I would put him at maybe 29 years old.

We bonded on a lot of things, though not everything.

He thought the police were corrupt from bottom to top. He thought the court system had nothing to do with justice and was a game for lawyers and judges. He thought the drug laws were ridiculous – it is legal to willy-nilly prescribe variations of heroin and cocaine for medical purposes but not marijuana.

He said he did not Vote in elections because the whole political and ruling system was corrupt. If he were to vote for anyone, he told me, he supposed it would be Jeremy Corbyn. I suggested maybe the Green Party and he was not averse to that but, as he thought the whole system was unworkable, there was no point.

I suggested, if there were a candidate or a party he thought had the correct policies and beliefs, then, by voting for them and increasing their majority even by one, he was giving them more profile and more visible backing – he should vote for them even if he believed they had no chance of winning.

“Like Jeremy Corbyn,” he suggested.

But he is not going to vote in elections because he believes the whole system is corrupt.

“Why do they give you pencils to mark the ballot paper in voting booths?” he asked me. “The people who mark you down as having voted and the people sitting outside the polling stations have pens. Why do they give you pencils to vote with? Pencils are more expensive than pens.”

I said I thought it odd that, as far as I know, when policemen write down statements, they are required to do it in pencil not pen. (I could be wrong that it is a requirement.)

He said he did not believe the Brexit vote to leave the European Union was correct. The vote was 52% to leave. “I think the real vote,” he told me, “was more like 90% to 10%.”

“In which way?” I asked.

“To leave,” he said. “No-one I know wants to be in Europe. The Scots have it right. They want to leave the UK because they don’t want this other place making decisions for them. They want to make their own decisions.”

Let’s leave aside the fact that a high percentage of Scots voted to remain in the European Union.

Given the fact that many people who voted ‘Remain’ in the Brexit referendum find it unacceptable that there was a ‘Leave’ vote because everyone they know voted ‘Remain’… I thought it was interesting that youngish Peter The Plumber, who shows all the signs of being a true Corbynite and an anti-Establishment Left-Winger could not believe that the ‘Leave’ vote was as low as 52%.

Everyone thinks they are ‘normal’ and average and that their mostly self-chosen circle of friends and acquaintances are the norm. Everyone thinks they know what the majority of ‘normal people’ think.

Everyone is almost always wrong because they see and hear in their own bubble of ’normality’.

And, yes, I know if I write ‘everyone’ I should not write ‘they’ and ’their’ – I should write ‘he or she’.

But let’s not be pedantic. It is normal to use ‘they’ to mean ‘he or she’. Isn’t it?

Well, it seems that way to me.
