You get into a talkative state by what else-- talking. Don't think too much about the first approach, be loose and just have fun with it. After that it should just come natural.

If there's any public gatherings, say a wedding, party, whatever, go for it. I've found it so much easier because everyone's talkative, and in a good mood. You can small talk your way at first and then just have a conversation.

Good luck.
