Not seen the movie.
Best friends is up and down. Had one definitive best friend who died around 5 years back and I've got a few clusters of friends, such as school pals, people I've been in bands with.
Though in the past year a bunch of work pals and old bandmates have come together and formed a new band just to have fun with, cos we're all getting on a bit and need a hobby I suppose. It's been really nice seeing them very often, bringing people from one element of my life into the fray with those from another.
I don't think I've felt more friendship than right now in a long time because of this!
Partner is a teacher in a deprived area and parents have physically engaged with teachers on more than one occasion.
But even in my job which has a publicly known phone number people are finding it perfectly reasonable to shout down the phone despite nothing having gone wrong with their process.
People are getting more aggressive and it'll be a mixture of things. Partially cos everything is fucked, but also, certainly in my case, things like Amazon have changed people's expectations. They get something the next day, if they don't like it they get a voucher no questions asked, or if they want they can scam the system.
Works fine for Amazon, doesn't work fine of you try to force that business model onto already stretched public services. If they're told their kid isn't behaving or performing they'll go on the attack and act like a shitty customer rather than a parent.
