Funny you say that because a lot of old literature has plenty of love used in non-romantic friendships.
The one that’s rough for me is the term best friend. I have a very tight group of 10ish people whom are all very dear to me. So I’ve had to rework whom I call a friend and who is just a good acquaintance.
Truth is that if I wouldn’t call you for help or if I wouldn’t expect a call from you when you need help, then we really aren’t friends. Some people may think that’s hurtful to say. But reality is that there are people I enjoy hanging out with but I’m not going to allow into that personal space. Friendship is something you build, not something that happens just because of proximity.
Its one of the issues with the english language. So many words are given a multitude of meanings to where it complicates things. I’m very fond of a lot of my common acquaintances and I’ll help out if they need it. But I’ll make myself a pretzel for a friend.
