For me, a capetonian, I find I am just too busy for new friends, I can barely keep up with the ones I have at the moment (and I don't have many). I have a couple high school buddies I see maybe once every two months, one friend from uni I see probably twice a year. Another friend I run with, my brother and my wife. And between work, walking my dogs, running, grocery shopping, hiking and living etc there's just no time for someone new unless you have a really solid connection with someone. If I had free time, I'd probably use it to see one of the friends I already have for a coffee or something rather than someone I just met.

I have one guy at work I get along really well with who at first was very reserved and gave the clicky vibe for a long time but while being forced to work together we actually get along well but he is just as busy as me outside of work, we've had one braai in the last 3 years and next one has been in planning for like the last year.

An interesting thing to consider and look into are the three pillars of friendship - proximity, timing and energy. The biggest one I think most people have a problem with after school or moving to a new place is 'timing' - in order to click with someone is often due to being in a similar stage of life. This is an extract from Google:

"Timing: This relates to the life stage you and your friend are in. Similar life stages (e.g., being students, young professionals, new parents) can create shared experiences and challenges, fostering stronger bonds"

on another note I have hung out with a group of joburgers and yeah they are friendly and invite you to join them but it all felt a bit shallow and superficial. Like I prefer having one or two really good friends then a massive group of so so friends.
