With respect, I think this is quite a sad and revealing comment, but your Hollywood definition of a friend fits my friends. I wonder if you maybe never experienced friendship but rather just acquaintances.
I’m 40. I didn’t throw down for my friends when I was 19, but I support those same friends through divorces, cancer, deaths now. They’ll do the same for me.
Some friends are closer than family. That’s luck, but also intention.
My best friend asks me what I had for lunch on random days. Sometimes I get drunk and message him how I was reminiscing about the good times together. Things don’t have to be as complex as you think. Just appreciating the simple stuff might go long way.
