I remember one of my teachers at school talking about friendships that have stood the test of time. I had a friendship that lasted 17 years and ended with her passing away.

Sometimes, you can have good friends who you you might only talk to a couple of times a year, but they're often in your thoughts, sometimes you can talk to people everyday and you can see and feel them shifting further away.

One thing that I say to people is, tastes, opinions and core values are not the same things. I mean two people might be friends at school and both go on to study law. Both are seemingly motivated by the same thing, but one ends up working for Legal Aid defending those unable to pay for a lawyer, and another is enticed by wealthy clients, and is driving a brand new BMW. And they might only meet occasionally, but they have nothing common.

Sometimes, you might have two people and one is a non-Trumpist Republican and the other a Democrat, but they go to the football together because they both like the same team.

Part of me was keen to reconnect with an old friend from primary school, but then I thought, "Okay, you were friends at school and haven't seen each other since 1983, and, a) he might get a message from Peter Wynn, and think, "Who's that?" "You went to school with me 38 years ago." "Oh, did I? Can't say I remember you." Or, b) he probably won't be the same person and I might not like who he is now.

I mean, it's 30 years since I graduated from high school, and we are having a reunion, and part of me says, "For some people, it'll be lovely to reconnect, but for some, a request to add them on Facebook might be met with, "I'm happy to see you at reunions and wish you good health in between times, but that doesn't extend to wanting you to be a regular part of my life.""
