Contracts end, money runs out, staff changes and more. That’s when people shift positions. Some go up, some go down. Some don’t change much. You cannot get angry if someone you are not used to seeing or hearing from takes a walk, starts talking, has a new presence. There are 8 billion people on planet Earth. In theory that’s 8 billion changes waiting to happen. Small, or big and so many things in between.
I admit, some people are NOT NICE and cause trouble. Some are nice and trouble tries to find them. There are enough of us to make the correct adjustments, I humbly suggest.
