Chill people are essentially low maintenance, and that can be nice if you already feel like you're dealing with too much. Past a point though you'll see that the chill types have very few plans in their lives and tend to just lump in one place, drifting with the flow instead of selfishly indulging in their own needs.
I find it worth chilling them out, as it often is as easy as being an active listener or just cultivating things that the established mutual voice between me and them both like. Basically, if I can make how I'm behaving synergize with the things they want as well, then they're basically chill while I've done very little to make it happen.
A lot of chilling out a "control freak" comes from cultivating the right environment. As long as what they want isn't that demanding it's like having a classier chill person.classiness to me isnt that interesting i prefer messy and different:) im glad that classiness exists and definitely like the basics such as proper hygiene and English but too much classiness is boring af to me
Control freaks can still be messy and different. What matters are what things they're so picky about. Some are actually surprisingly unclean (ie: the unshowered geek archetype).
Effectively, by "classiness" I mean they actually take more time to think about things from already having a faster paced brain. Chill people often have the ability to just shut thinking off, or at least partition it, and from having less mental snags their answers to questions tend to be... simpler.
I like complications, as long as they don't become mine.
