How do you make a modded follower to have sporadic conversations with other NPCs?

Hi, 

I'm a noob modder who have no idea what I am doing. ~.~

Everything looks so complicated!

 

So, here's my question.

When you travel around the commonwealth with your companion, they often start conversations with other NPCs.

For instance, Preston gets admired by someone who thinks minutemen are doing some great work out there.

I really wish to know how these events are triggered, and how to add new triggers like these.

I've watched some of Kinggath's wonderful videos on YouTube, but I couldn't find this exact topic. 

 

Thank you for your time.

Thank you for directing me to some very nice materials.

I closely followed the video, but somehow failed to make my actively following companions to talk with other NPCs. 

Gotta have some more trials & errors I guess.
