What are the best ways to socialize that don't involve alcohol or drugs?

I know this seems obvious and is still a bold move, but listen with me here. Table Topics- ever heard of them? If you struggle to start a conversation with someone, these are perfect. Obviously, Please, do not ask personal questions to someone you just met. Start off my greeting yourself and asking how they are. Then, ask a question that requires a 2-3 sentence response ( What are your opinions on ___? How do you feel about ____? In your own words, define ____. What does _____ mean to you? ). Try to make these questions make someone think. When you find something you both agree on, try talking about that. Try to get into a deep, but not personal conversation. Even better, try to make your Table topics questions related to a theme ( a theme can be anything, it could be about the place you're in, anything relevant ). As someone who struggles with social interaction, this has helped me a lot. I hope it can help you too.
