How to Start a Conversation in Spanish

How can you start a conversation in Spanish? This is one of the trickiest things for me in Spanish right now. There are two kind of props that we can use. If someone has kids, this works all the time for me. I think when I use that phrase, like, oh, I need to practice my Spanish,. That disarms, it pulls down walls and people realize there's no judgment here. It's good.
