From Long Way to a Small, Angry Planet by Becky Chambers (p.135)

“Yeah, stuff that’s really important or hard to say. Like about love or hate or stuff you’re scared about. You know how when you have something big to tell someone, you stammer through it or sit in front of your mirror practicing what to say? Aandrisks don’t bother with that. They let the gestures take care of all the awkwards. They figure that big, deep feelings are universal enough to be defined with just a flick of the hand or whatever, even though the events that cause those feelings are unique.”
