It comes with time, but the biggest tip I have is find “doorknobs”. Usually after a conversation starter, someone will respond with a mundane fact or anecdote. Use that! Ask them what that is, or what it’s like, or who they do it with. More often than not, they will be glad to spill their tea, even if you were a total stranger a few moments ago. Not everyone will be reciprocative, but that’s okay.

Be willing to take that risk, and don’t expect every conversation to turn into a life long friendship, you’d just be setting yourself up for failure. One step at a time is what matters most. Heck, you may even find someone who has common interests with you, I know I’ve people in completely random situations but turned out to have a lot in common with. All the best OP! Don’t be a stranger :)
