Sure it can happen like that, but it's not the only way. No effort is required to begin a friendship that happens automatically. Both naturally organise a next meet, and/or already have reason to and/or happily can't avoid it. Relationships often begin at work/edu for this reason. The times I've been assertive and essentially built a connection out of what was nothing, it's been interesting, even exhilarating - but less reliably enduring. It's tended to be better to begin with a bigger "spark". And if that spark isn't enough to create a shared excitement that automatically leads to a next step, without requiring effort, it may mean it's not worth such effort. (Not always, though.)
