The other day, Lime and I saw some young women in Seoul, near Hong Ik University, holding up a Free Hug sign. Lime told me it was a new big trend in Seoul.
I see it’s not a native invention, however.
That it’s not native isn’t a criticism, mind: I think anything that makes people more relaxed about public friendliness and displays of respectful affection are a good thing, in any society.
