That's an honest and thoughtful answer :)

I'm only a decade older than you, but when I look back over that decade it feels like everything's changed. I've made new friends through hobbies, music, sports and yes, the workplace. I've lost touch with some people I thought were close friends. I've also been surprised by getting back in touch with people from school or university who I thought I might never hear from again.

Would I lie for those people in court (or vice versa)? I dunno. It's kind of a weird litmus test, because it depends on one's principles, how serious the charge is, and one's perspective on the legal system. It could happen, but I could only answer on a case by case basis. It's possible that I'd lie in court for a complete stranger if the circumstances were right. I struggle with absolutist views like "This is what friendship means and I will 100% behave in this way if that situation arises".

How would I define "friend" as opposed to "acquaintance"? Possibly as simple as: someone that you spend time with just for the enjoyment of it. If they're a work colleague, this means that you're likely to meet up socially, away from the office and work events (even if just online). Otherwise you're there because you have to be.
