I don't know, I have made friends well into my adult life, including after having kids. Granted it is not in the same frequency as in the uni days but still during the years I have found some. Mostly people I have bumped into at work but were not directly above or below me or via other friends who introduced me to their friends. I am not an extrovert or too introvert and I don't know why it seems like everyone here must declare themselves as if they are in the extreme of this bell curve, probably they are somewhere in the middle, like the rest of us.

I think this is highly dependent on luck. If you're friendly and happen to live near other, outgoing, friendly families, then the odds of befriending them are higher. It also helps to have a friendly spouse (it helps a LOT).

Luck is an interesting element.

My best friend for 20 years (we've since fallen out of touch), was someone I met in kindergarten?

How did we become friends?

My surname starts with a "G" and his starts with an "H" so we were seated next to each other

I met someone at Strangeloop because they were a doppelganger of an acquaintance from some years previously. I now realize that I had this attitude like we already friends because of that unrealized similarity. Attitude and any alignment in interests is more than enough, or alphabetical. :)

"Uncommon Commonalities" are wild.

There was a girl who I couldn't stand in high school... but we bumped into each other in a train station on the opposite side of the country... and hung out all afternoon.

Just being from the same small town made an immediate (but brief) connection

I had the same experience in 6th grade with a friend who moved to Michigan from Iowa. Last names "M" and "O" put us next to each other in class and the rest is history I suppose.

It feels corny to say, but you really can't make old friends.
