How do you Deal with people you don't like?

[BaconAndAvocado]

This is a strange one.

There's a parent I really can't stand; they are rude, constantly moaning and miserable. Thankfully, I won't have to see him again on a regular basis as it was my son's last day at primary school yesterday.

This parent also lives very near me so I may bump into him sometimes.

A few years ago,I suffered from low level anxiety and I can feel it rearing up again when I see him. I worry whether he's going to say hello or ignore me.

I know this all sounds utterly crazy as, as I've said - I can't stand the guy.

I don't know why I'm letting this idiot affect me so much!

Can anyone shed any light on why I feel like this?

Generally smile, say “Morning!” (or whatever ) and move on!

I already do this but, for some unknown reason, I get really pissed off with how he behaves.

I know this is ridiculous! And I know that I have to stop this as it's not something I can control, or actually any of my business!

I guess I should really feel sorry for him (and his poor wife who is quite a nice person). He's probably the way he is for a reason.

As I'm writing this, it seems so stupid to be using all this time and energy worrying about a person I dislike.
